Synopsis
Official Name: IncO1Exp
BCALL Address: 426A
Increments OP1's exponent.
Inputs
- OP1 = floating point number
Outputs
- OP1 's exponent incremented
Destroys
- A
Comments
This function increments the exponent of OP1. Checks are not performed to prevent an overflow.
Example
Suppose OP1=00h,80h,10h,00h,... After B_CALL IncO1Exp, OP1=00h,81h,10h,00h,... Suppose OP1=00h,FFh,10h,00h,... After B_CALL IncO1Exp, OP1=00h,00h,10h,00h,...
