fixatan

Fixed point inverse tangent lookup table.

Description

This function finds the inverse tangent of a value using a lookup table. The input value must be a fixed point radian. The inverse tangent is the value whose tangent is `x'. Example:
      fixed result;

/* Sets `result' to binary angle 13. */ result = fixatan(ftofix(0.326));
Returns the inverse tangent of a fixed point value, measured as a fixed point binary format angle.
