Usage COMPLEX Z,C

C=FNCloggamma(Z)

Description

FNCloggamma returns the value of the logarithm of the gamma function of the complex value z, log[Γ(z)]. The value of log[Γ(z)] approaches ± as z approaches a negative real integer or zero.

Errors

FNCloggamma causes an HTBasic error if its argument is not of type COMPLEX or if the magnitude of either the real or imaginary component of log[Γ(z)] exceeds MAXREAL, the largest number representable.
