may be available only with certain extended compilers.
Compute the pair-precision sine of x.
None. The function result is stored in the first argument,
result.
Trigonometric functions are computed by reducing the argument to a
multiple of pi or 2pi plus a small remainder, and the function is
then computed for that remainder. The finite precision of computer
arithmetic limits the precision of the remainder for large-magnitude
arguments, and eventually, all accuracy is lost, and the function
value is effectively meaningless. In practical applications, it is
usually possible to eliminate large arguments by exact mathematical
reduction before doing a computation.
None.
