Tangent
Most Sirius $functions have been deprecated in favor of Object Oriented methods. There is currently no direct OO equivalent for the $Tan function.
The $Tan function returns the tangent of an argument that is given in radians. If the magnitude of the argument exceeds 1015 radians, an error message is printed and a 0 is returned.
Syntax
%num = $Tan(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.
