NAME

       fixsin - Fixed point sine of binary angles. Allegro game programming library.

SYNOPSIS

       #include <allegro.h>

       fixed fixsin(fixed x);

DESCRIPTION

       This  function  finds  the  sine  of  a value using a lookup table. The input value must be a fixed point
       binary angle. Example:

          fixed angle;
          int result;

          /* Set the binary angle to 90 degrees. */
          angle = itofix(64);
          /* The sine of 90 degrees is one. */
          result = fixtoi(fixsin(angle));
          ASSERT(result == 1);

RETURN VALUE

       Returns the sine of a fixed point binary format angle. The return value will be in radians.
