   9     FUNCTION
  10       Calculate the cosine and the sine of the given ffp-number
  11       fnum1 that represents an angle in radians. The function
  12       returns the sine of that number as a result and puts
  13       the cosine of that number into *pfnum2 which must represent
  14       a valid pointer to a ffp-number.
  15
  16     RESULT
  17       *pfnum2       - Motorola fast floating point number
  18       direct result - Motorola fast floating point number
