Usage COMPLEX Z,C

C=FNCerfc(Z)

Description

FNCerfc returns the value of the complementary error function of the complex value z, erfc(z). The imaginary part of the value of erfc(z) approaches if the real part of z is zero and the magnitude of the imaginary part of z becomes large.

Erfc(z) is related to the error function returned by the FNCerf function, erf(z), by the expression

Errors

FNCerfc causes an HTBasic error if its argument is not of type COMPLEX or if the magnitude of erfc(z) exceeds MAXREAL, the largest number representable.
