Softw., 19 (1): 22–32, doi:10.1145/151271.151273 ^ Zaghloul, M. Related functions[edit] The error function is essentially identical to the standard normal cumulative distribution function, denoted Φ, also named norm(x) by software languages, as they differ only by scaling and translation. New York: Dover, pp.297-309, 1972. http://jamisonsoftware.com/error-function/gaussian-error-function-ti-89.php

A two-argument form giving is also implemented as Erf[z0, z1]. When the error function is evaluated for arbitrary complex arguments z, the resulting complex error function is usually discussed in scaled form as the Faddeeva function: w ( z ) = The pairs of functions {erff(),erfcf()} and {erfl(),erfcl()} take and return values of type float and long double respectively.
