al_fixsin
al_fixed al_fixsin(al_fixed x);
Introduced in 5.0.0
This function finds the sine of a value using a lookup table. The input value must be a fixed point binary angle.
Example:
al_fixed angle;
int result;
/* Set the binary angle to 90 degrees. */
angle = al_itofix(64);
/* The sine of 90 degrees is one. */
result = al_fixtoi(al_fixsin(angle));
assert(result == 1);
Return value: Returns the sine of a fixed point binary format angle. The return value will be in radians.
