Math Expressions

A lil one class library to quickly evaluate simple math expressions. Or just to parse it and apply syntax highlighting.

How 2 Use

(just click the jitpack badge)

Use the MathExpression#parse method to get an instance of MathExpression. Think of this like compiling ahead of time. The required argument is the string of the expression (i.e. 19 * 12). You may also provide a map of string (name of variable) and double (value of variable) as an optional second argument. Alternatively, you can set a variable by invoking MathExpression#setVariable (chainable method), which takes a string and double. All of the constants in the JDK Math class are added automatically as built-in variables (i.e. PI). Once you are ready, simply invoke MathExpression#evaluate. You may invoke the method multiple times with different values for the variables.
