CosF32
Computes the operamath 32.32 cosine of a 16.16 fraction.
Synopsis
frac32 CosF32( frac32 *c, frac16 x )
Description
This macro returns the operamath 32.32 cosine of a 16.16 fraction. In operamath coordinates, there are 256.0 units in a circle.
The macro actually calls the SinF32() function with one quarter circle added to the input value.
Arguments
- c
- A pointer to a 32.32 fraction containing the result.
- x
- A 16.16 fraction describing the angle of the circle.
Return Value
The macro returns the cosine of the input angle.
Implementation
Macro implemented in operamath.h V20.
