Overview

Syntax: es_mathparse <output-variable> "<math-expression>"

Note: Command parameters are described inside the < and > characters. Optional parameters are contained within [ and ] characters.

Variation of this command that doesn't expand variables: es_xmathparse

Stores the result of a mathmatical expression in the output variable.

output-variable - Stores the output of the mathmatical expression
math-expression - A mathmatical expression of numbers, server variables, and common mathmatical functions.

es_mathparse myvar "4*sin(30)+log(sv_gravity)"

myvar "myvar" "-1.049037" ( def. "" ) - Custom server variable.

Server variables can be referenced with their raw names. They do not need "server_var" to resolve. (e.g. "3 + mp_flashlight")
This command makes use of the muParser library for math text parsing. Refer to its documentation for special cases, etc.
Supports some constants like _pi and _e.
Also supports the unary ! operator (not) to return the boolean opposite of the value.
This command was first introduced in EventScripts v1.3.
