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.
