Description[edit]
This is an ACS built-in function.
Computes the cosine function.
Usage[edit]
fixed cos(fixed angle)
Parameters[edit]
- angle: the fixed point angle (0 means east, 0.25 or 16384 means north, 0.5 or 32768 west, 0.75 or 49152 south)
Return value[edit]
Examples[edit]
No examples given.
Notes[edit]
This uses Doom's classic (but perfectly deterministic) approximate trigonometrics, so there will be slight errors noticeable when pointing at orthogonal angles.
This function's identification in zspecial.acs is: ACS internal.
