    Description: This function calculates the angle of the vector (x,y)
    based on a table lookup and linear interpolation. The table uses a
-   256 point table covering -45 to +45 degrees and uses symetry to
+   256 point table covering -45 to +45 degrees and uses symmetry to
    determine the final angle value in the range of -180 to 180
    degrees. Note that this function uses the small angle approximation
    for values close to zero. This routine calculates the arc tangent
