Synopsis
Official Name: FDiv100
BCALL Address: 4261
Performs a fast divide by 100 on OP1.
Inputs
- OP1 = floating point number
Outputs
- OP1 = OP1 / 100
Registers Destroyed
- A
Comments
This function divides OP1 by 100. This is done by twice decrementing the exponent. Checks are performed to prevent an underflow. This is much faster than FPDiv when op2=100.
Example
Suppose OP1=00h,80h,10h,00h,... After B_CALL FDiv100, OP1=00h,7Eh,10h,00h,...
