The implementation is based on table lookup using 256 values together with linear interpolation. The implementation is based on table lookup using 512 values together with linear interpolation.
The steps used are: The steps used are:

-# Compute the fractional portion (fract) of the table index. -# Compute the fractional portion (fract) of the table index.
