math_atan is a global callable that can be used wherever an expression is valid. math_atan is part of numeric expression work. Be deliberate about integer versus decimal inputs because several math helpers preserve or infer the result type from their arguments.

Parameters

value: Required value. Supply value positionally unless the signature shows a keyword form.

Examples

Basic call
