FNCbetareturns the value of the beta function of the complex valuesaandb,B(a,b).B(a,b) is defined as (a)(b)/(a+b) (seeGamma).B(a,b) is only defined fore(a) > 0 ande(b) > 0.
Errors
FNCbetacauses an HTBasic error if its arguments are not all of type COMPLEX, or if the real part of eitheraorbis negative or zero.
