Synopsis
Official Name: Cos
BCALL Address: 40C0
Computes the cosine of OP1 and returns the result in OP1.
Inputs
- OP1 = floating point value
Outputs
- OP1 = cosine of OP1
Destroys
- AF, BC, DE, HL
- OP1-OP5
Comments
Takes approximately 150,000 to 200,000 clock cycles.
Example
B_CALL OP1Set3 ;OP1=floating point 3 B_CALL Cos ;returns with OP1=-0.9899924...
