# Exponential Format

Apr 25, 2008
I am working with a program that creates numbers as follows:

Instead of -2.74E-6, the program writes -2.74-6. The E is left off to save space.

When I import this data, Excel automatically "does the math" so the cell reads: -8.74 instead of -2.74E-6.

In excel if it changes number to exponential format it would default to, for example if number is 12345 -> 1.2345e4, 0.012345 ->1.2345e-2

I was wondering it is possible to which a function to change this default format ie for example 0.012345 -> 12.345e-3

I basically want this kind of formatting as its would display information in terms of milli, micro, pico (or the opposite side kilo, mega, giga and so on).

I have the following data

A1 - 65.23

A2 - 1923.52

A3 - 945.18

A4 - 182.54

In column B

B1 =exp(A1)

B4 =exp(A4)

both are fine, however

B2 =exp(A2) - it is showing #NUM

B3 =exp(A3) - it is showing #NUM

Same case for all larger numbers

I have inherited a series of data relating to a change in a specification over a period of time and a number of cycles.

See attached.

There is already a chart which shows the data and has an exponential line.

I want to find the value of Cycles where the Average Flash exponential from the chart line is 0.131.

FYI this is to plot deterioration in a piece of tooling, 0.131 being the accepted warning level. If you feel there is a better statistical model to use for that application then I'm all ears!

I have a frequency table (attached) that I need to be able to interpolate values between the known values on something other than a linear basis (e.g. exponential or logarithmic).

interpolating numbers in excel for an exponential function. I want to know how to be able to curve a curve in 4 different ways essentially the 2 that make up the two halves of a peak and the 2 that make up the two halves of a trough. I've tried using the LINEST function to create this interpolation and it's good to get 1 of the 4 curves I'm interested in. how to do the other 3? I'm also interested in knowing if these functions "whip the tail up" as in almost like how the tail end of a "sin" function flips back up. here it is.

[URL]

For this example of the exponential function, it creates the curve in one particular direction. I was wondering how I would do it to have it curve in another direction, for example I was testing the same function, but going downwards, and also having the tail curve back up (by hump I mean to simulate a gaussian distribution with the tails) how would I do that. seems like I now have part 1 of 4 aspects of the curve. here's the attached file to show what I mean. I want to get the hump going up and then sort of reflected along the y-axis and then similar features if I were to reflect the curves on the x axis. is it possible with the functions in excel?

I have some short code that imports data and account numbers that is "|" delimited. The problem I am having is that during the import, excel converts some of the account numbers to exponential numbers.

e.g. it converts 542690E24 to 5.4269E+29.

Is there a way to avoid this from occuring during the import? I tried to format the destination cells as '000000000' (all accounts are 9 digits) but it didn't work.

to write a function that will exponentially weight a series of returns by a certain decay factor.

I have excel spreadsheets that can do this over several columns, like this

series of returns... rtns squared

2.50% =2.50%*2.50%

3.50% =3.50%*3.50%

5.00% =5.00%*5.00%

1.01% =1.01%*1.01%

0.75% =0.75%*0.75%

4.01% =4.01%*4.01%

-2.78% =-2.78%*-2.78%

I've been working on a ss that requires me to create a function to determine a value from a exponential curve where the area of the curve is variable . The terminal points, 0,0 and 100,100 remain constant and the curve is symmetrical at the 45degree angle. How can I derive a function knowing only these things.

Here is an image to crudely illustrate what i mean [url]

The area can be 10, 20, 35% it doesn't matter, I need a way to determine the function from just the area!

I am trying to find the exponential equation from a set of data in excel. The problem is that the graph does not follow the scatter plotted points on the graph. How would you remedy this?

I have a bit of code that is grabbing only the first 9 positions of an alpha-numeric string. The problem I am running into is that when the alpha-numberic value contains an "E", the code turns it into an exponential number in error.

For example, I have the following in column G: 01877E107000. When I run the code, it turns into an alpha-numeric value. The result should be 01877E107 (in column K). I tried using the text function within the code.

I was wondering if anyone could tell me how to do away with the "Exponential" appearance of numbers (in Excel) when they are formatted as text. I am working with National Stock Numbers and there are no required computations based on them being formatted as a number ... AND ... one of my constraints is that they are required to be formatted as text when imported into an Access database ...

I use hex2dec frequently and input with a hex 'E' such as 05e8 is misinterpreted as exponential notation. I can use =hex2dec("05e8") to get the correct value, but when the hex number is in another cell, I get the exponent assumption/ conversion (to 5 x 10e8), or a # NUM error if it is in quotes. This seems like a blatant problem but I've found no mention of it in searches or FAQs.

I have created a userform but I am having extensive problems with the date formats.

My system is set to UK and short date is set to: DD/MM/YYYY

When I used code to add the values in the userform to the spreadsheet, any that contained a date format would revert to the US format.

So I finally figured out to use DateValue to format it correctly for example: ...

I have a column of cells with values - 0.2%, 0.32%, 0.22, 0.5 etc. The cells with % symbol are in ' Percentage, 2 decimal' format while the plain numbers are in 'General' format i.e. column contains cells in either of these formats. I need a macro where I can specify the column and it will select the cells with the % format, convert it to 'General' and multiply the result by 100 eg. 0.2% converted to 'General' becomes 0.002. When multiplied by 100, result is 0.2 i.e. is displayed without the % symbol.

One of the reports I run provides me information on lengths of time. Such a field displays as |0:09:16| indicating 9 minutes and 16 seconds. However, when the report generates the excel spreadsheet it saves these cells in date/time format ([h]:mm:ss). If I were to convert this field to the number format (so I can manipulate and graph it) it displays as such |0.00643460648148148| Ideally I would be able to have the data in the field stored as |556| (556 seconds, or 9 minutes 16 seconds). I have thousands of fields that I need to manipulate where the data is stored in this format and I can not figure out how to fix it.

How can I format cells to contain Minutes, Seconds and Hundredths of seconds to be used in calculations eg 1.24.99 means 1 minute and 24.99 seconds. Example calculation is: 1.24.99 - 1.24.90 =0.0.09

I need to format some climatic data from a weather station into a desired format. There are a lot of cut&paste and transposing involved. I think it will be easy but tedious for anyone trained in VB to write a macro but unfortunately I am not. I've tried recording a macro but it turns out that it is not general enough to deal with all the spreadsheets that I've got.

I've attached a spreadsheet which shows the original format (in sheet 1) and the desired format (in sheet 2). To briefly describe, I only need the temperature data for 8am and 2pm, the rest of the information in sheet 1 is useless to me.

Every month, I have an import a report to a spreadsheet. At my column A, it supposed to be a date format.

For some reasons, I have a combination of a few cells of date format and a few cells of general format with no order at all.

What I need is: Search in the A column, if date format leave it , if not change from general to date format.

I have an Excel 2010 spreadsheet where the default number format keeps switching to the date format. I keep switching it back and it'll stay as a number format for a time, but then it'll switch back. This is also the case for any new worksheets in that one spreadsheet.

This only happens with this one file - everything else behaves according to my regional settings or to how the file had been previously formatted.

I have a Sheet ( Named "Summary" for Example ) of about 4,000 Rows that has a LOT of Conditional Formatting.

I Added Another 100 Rows this Morning and when I Tried Saving it a Message Saying that Not All the Formatting for the New Data that had Been Added had Been Saved. Is there a Macro or Something I can Run that will Make the Conditionally Formatted Cells Stay the Colour that they are but Delete the Conditional Formatting Part of it Achieved Using "Format" & "Conditional Format" from the Menu Please.

Ideally I would like to be Able to Enter the Number of Rows ( From Row ? to Row ? ) that I want this to Apply to.

I have a forecast which is sorted by product code by week vertically. I need to create a lookup to re-format this information into a horizontal format by week. I have started this by transposing the information as my attachment shows but I am hoping there is a lookup formula which will be easier and quicker. I have attached the actual document and the data I want to sort is Sheet 2. I have started in Sheet 1. I want to look up the code in column A, then lookup the week number which would be B2 in Sheet 1 and return the value of that Code in that week from Sheet 1.

I would like to have a single button that changes a range of cells from the USD to EURO to perhaps CAD symbol. Can this operation be performed, such that if I start in dollars, and I click the button once, it shifts by range to EURO (not formulas...just symbol)...and then if I click the same button again, it goes to CAD, and then back to USD with a third click?

In order to export an excel table into another program I first need to save the excel file as .txt. The .txt file can then be imported by the other program.

First I however need to make excel understand that the value should be a text and not a value. I therefore format the number as text (0000150235) by adding "0000150235". After saving the file as .txt the format changes from "0000150235" to """0000150235""". I do however need the format in the .txt file to be "0000150235". Can anyone tell me how I can save "0000150235" as .txt and get the value "0000150235" in the .txt file.

I'm trying to format my email generated of excel sheet to have an HTML formal before they are sent out using MS Outlook.

I have googled, searched your forums and also tried to figure out a solution with the existing helps on the internet. I need help on how to format emails genarated out of my excel sheet. I know a bit of HTML syntax but a newbie to VBA. I'm guessing the formatting has to be done in the Emailbody text function in my code.

I'm also trying to understand the logic behind the code and also learning excel vba bit by bit at the minute.

I have two columns where there are dates (e.g. 11/05/2009) in a date format; I would like to change the format to `general`; but without losing the original values, i.e. I still want to see 11/05/2009, but just in `general`format. Is it possible to create a macro that will do that? I want these values to stay in the same place, i.e. if it is in cell K10, I still want to have it there - just in other format.

I have a some dates in a format which are not being converted into the normal date format. So i made this formula to convert it into the normal date format:

=IF(LEN(B218)=10,(MID(B218,4,2)&"/"&LEFT(B218,2)&"/"&RIGHT(B218,4))+0,IF(LEN(B218)=9,(MID(B218,3,2)&"/"&LEFT(B218,1)&"/"&RIGHT(B218,4))+0,IF(LEN(B218)=8,(MID(B218,3,1)&"/"&LEFT(B218,1)&"/"&RIGHT(B218,4))+0,"")))

Formula is working fine except on this type of date "9/9/2013"..i also tried an OR formula with mid but didnt get the desired result.These are the type of dates:

12/10/2013

12/9/2013

9/11/2013

9/9/2013

7/25/2013

I have an excel sheet full of dates in text format and want to convert them into regular format. For instance, one of the dates listed is in text as "60801". I'd like it to show in regular date format of mm/dd/yyyy, so that 60801 becomes 8/1/2006.
