Synopsis
Official Name: InvSub
BCALL Address: 4063
Computes the floating point subtraction OP2-OP1.
Inputs
- OP1 = floating point number
- OP2 = floating point number
Outputs
- OP1 = OP2-OP1
Registers Destroyed
- AF, BC, DE, HL
Comments
This is similar to FPsub.
Example
Suppose OP1=00h,80h,12h,00h,... And OP2=00h,80h,10h,00h,... After B_CALL InvSub, OP1=80h,7Fh,20h,00h,... Suppose OP1=00h,80h,10h,00h,... And OP2=00h,80h,12h,00h,... After B_CALL InvSub, OP1=00h,7Fh,20h,00h,...
