DescriptionYi = sin( (Pi / q) * p )
The sine of fractional multiples of p is calculated. There are three versions: VF_sinrpi is for general use with any arbitrary denominator q. If q is a power of 2, VF_sinrpi2 should be used which is a highly optimized version reading the results from a look-up table, if possible. If q is a multiple of 3, VF_sinrpi3 should be used. VF_sinrpi3 offers a convenient way to use degrees instead of radians; if, for example, q is 180, then the unit of the elements of P is "degree". VF_sinrpi2 and VF_sinrpi3 work also with q values they are not optimized for; in this case, however, memory space is wasted for the tables.
Error handlingThese functions should be error-proof, as long as q!=0.
Return valuealways FALSE (0)
