  21 /*  FUNCTION
  22         Calculate the cosine and the sine of the given ffp-number
  23         fnum1 that represents an angle in radians. The function
  24         returns the sine of that number as a result and puts
  25         the cosine of that number into *pfnum2 which must represent
  26         a valid pointer to a ffp-number.
