BCALL Address: 4267
Decrements op1's exponent.
Inputs
- op1 = floating point number
Outputs
- op1 's exponent decremented
Registers Destroyed

Comments
This function decrements the exponent of op1. Unlike FDiv10, checks are not performed to prevent an underflow.
Example
Suppose op1=00h,80h,10h,00h,... After B_CALL FDiv100, op1=00h,7Fh,10h,00h,...
Suppose op1=00h,00h,10h,00h,...
After B_CALL FDiv100, op1=00h,FFh,10h,00h,...
