double IEEEDPSincos(
double * z,
double y );
Calculate the cosine and the sine of the given IEEE double
precision number where y represents an angle in radians. The
function returns the sine of that number as a result and puts
the cosine of that number into *z which must represent
a valid pointer to a IEEE double precision number.
*z - IEEE double precision floating point number
direct result - IEEE double precision floating point number
