FNCerfreturns the value of the error function of the complex valuez, erf(z). The imaginary part of the value of erf(z) approaches ± if the real part ofzis zero and the magnitude of the imaginary part ofzbecomes large.
Errors
FNCerfcauses an HTBasic error if its argument is not of type COMPLEX or if the magnitude of either the real or imaginary component of erf(z) exceeds MAXREAL, the largest number representable.
