Function	Description	Example
add	Adds two numbers.	{{add 1 2}} → 3
	If one of the numbers is a float, the result is a float.	{{add 1.1 2}} → 3.1
sub	Subtracts two numbers.	{{sub 3 2}} → 1
	If one of the numbers is a float, the result is a float.	{{sub 3 2.5}} → 0.5
mul	Multiplies two numbers.	{{mul 2 3}} → 6
	If one of the numbers is a float, the result is a float.	{{mul 2 3.1}} → 6.2
div	Divides two numbers.	{{div 6 3}} → 2
		{{div 6 4}} → 1
	If one of the numbers is a float, the result is a float.	{{div 6 4.0}} → 1.5
mod	Modulus of two integers.	{{mod 15 3}} → 0
modBool	Boolean of modulus of two integers. Evaluates to true if result equals 0.	{{modBool 15 3}} → true
