Fixed point inverse tangent lookup table.
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:
/* 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.
