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...
