function VF_coth( Y, X:fVector; size:UIntSize ): IntBool;
function VFx_coth( Y, X:fVector; size:UIntSize; A, B, C:Single ): IntBool;
Descriptionnormal versions: Yi = coth ( Xi )
expanded versions: Yi = C * coth ( A*Xi+B )
Error handlingSING errors lead to a default result of 0.0 (the mean of +HUGE_VAL and -HUGE_VAL); OVERFLOW errors lead to a default result of ±HUGE_VAL.
Return valueFALSE (0), if no error occurred, otherwise TRUE (non-zero).
