Description

normal versions: Y_i = sin( X_i )
expanded versions: Y_i = C * sin( A*X_i+B )
For large values of X_i, round-off error becomes appreciable; if the X_i values are representable as fractional multiples of p, it is better to use VF_sinrpi than VF_sin.
If, on the other hand, one can be sure that all X_i are within the range -2p <= X_i <= +2p, one can employ the faster reduced-range versions with the prefixes VFr_ and VFrx_.

Error handling

Precision errors lead to a default result of 0.0 and a non-zero return value, but are ignored otherwise; _matherr is not called.
OVERFLOW errors can only occur in the complex versions and lead to a result of ±HUGE_VAL.

Return value

FALSE (0), if no error occurred, otherwise TRUE (non-zero)
