Overview
Tap supports a number of common math functions. The key thing with the math functions, as with any function, is they are written inside parenthesis with the operator first.
Any value within a math function can be replaced with other math functions, as in: (+ (- 41 1) 2). Which is more commonly noted as (41 - 1 + 2). Tap uses the former notation to make it easier to combine more advanced formula functions.
