$ErfC

Error function complement

Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $ErfC function.

The $ErfC function returns 1 - the $Erf value, that is:

1 − 2/√π ₀∫^x e^-z2 dz

Syntax

%num = $ErfC(x)

See the SIRFUNC EXEC parameter for an explanation of when this high-performance, high-precision version of the IBM mathematical function from the Sirius Mods is used, as opposed to the version of the $function in the Model 204 FUND or FUNDLE CSECT.
