Log function

Most Sirius $functions have been deprecated in favor of Object Oriented methods. The OO equivalent for the $Log function is the LogE function.

The $Log function (or its alias, $Log_e) returns the natural logarithm (the logarithm base e) of the number x.

Syntax

%num = $Log(x)

%num = $Log_e(x)

If x is not greater than 0, 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.
