Error function
Note: Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $Erf function.
The $Erf function returns the value:
2/√π 0∫x e-z2 dz
Syntax
%num = $Erf(x)
Usage notes
- 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.
