4. D00103 and the result word, CIO 0011, are cleared to 0000 0000.
5. The result of the square root calculation is divided by 100, with the integer
portion written to CIO 0011 and the remainder going to D00103.
6. If the content of D00103 is greater than 4900, CIO 0011 is incremented by
1. In this case, the result is 78.

Purpose Calculates the sine, cosine, or a linear extrapolation of the source data.
The linear extrapolation function allows any relationship between X and Y to
be approximated with line segments.
