Exponential function
Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Exp function is the AntilogE function.
The $Exp function (or its alias, $Exp_e) returns the
value ex.
Syntax
%num = $Exp[_e](x)
If x exceeds 174.63, an error message is printed and a 0 is returned.
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.
