Rate Numbers Based On Numeric Range

In the attached excel file in column C, beginning on row 4, are numbers. These numbers will automatically update on my bloomberg terminal.

(1) I would like to then in column E to have a rating given to those numbers based on the below scale. The way the scale works is that if its 0.6 its a 10. If its anything slightly above 0.6 exactly, its a 9. A 10 is also a 0.5 and any number in between 0.5 and 0.6. The scale is below.

(2) Given that the formula that is being updated is a bloomberg excel formula (in the attached document I pasted it as values), will an excel formula be able to read the updated number in the bloomberg formula? If not, in column D is there a way to have it automatically paste D as values (and update each time column C changes or workbook is saved), and then have column E read off of those numbers.
Scale:

10 = 0.5 to 0.6
9 = 0.6 to 0.7
8 = 0.7 to 0.8
7= 0.8 to 0.9
6 = 0.9 to 1.0
5= 1.0 to 1.1
4= 1.1 to 1.2
3= 1.2 to 1.3
2= 1.3 to 1.4
1= 1.4 to 1.5
0 = anything greater than 1.5
