Binary (concatenated From Decimal) To Hex Conversion Error

I am taking a decimal degree (longitude) and converting it to binary then to hexadecimal. The value I am using is a Binary Angle 32 bit structure that will be translated into an 4-byte hexadecimal (with two characters per byte i.e. "20" is one byte and results in spaces).

This is what I have:

Input of 359.999999916 (in cell A2)
Cells B2 through AG2 I have converted A2 into binary (using formulas like "=IF(A2-180>0,1,0)" for cell B2, "=IF(A2-180*B2-90>0,1,0)" for cell C2, "=IF(A2-180*B2-90*C2-45>0,1,0)" for cell D2, and so on)

I then concatenated all of the results into one cell using the following formula:
=CONCATENATE(B2,C2,D2,E2,F2,G2,H2,I2,J2,K2,L2,M2,N2,O2,P2,Q2,R2,S2,T2,U2,V2,W2,X2,Y2,Z2,AA2,AB2,AC2,AD2,AE2,AF2,AG2)

To get a result of (located in cell A4):
11111111111111111111111111111110

However, when I attempted to use the BIN2HEX conversion on A4, I get a "NUM!" error. Here is the formula that I was using in cell A5:
=BIN2HEX(A4,8)
