It also includes other general purpose ones.

Name	Description	Usage	Result
in	Returns whether an element is in a set of values.	in(1 + 1, 1, 2, 3)	true
if	Returns a value based on a condition.	if(3 % 2 = 1, 5, 10)	5

Operators

Expressions can be combined using operators. Each operator as a precedence priority. Here is the list of those expression's priority.

Logical

These operators can do some logical comparison between other expressions:

Code:

  true or false and true

The *and* operator has more priority than the *or*, thus in the example above, *false and true* is evaluated first.

Relational

Code:

  1 < 2

Additive

Code:

1 + 2 - 3

Multiplicative

Code:

 1 * 2 % 3

Bitwise

& (bitwise and), | (bitwise or), ^(bitwise xor), << (left shift), >>(right shift)

Code:

  2 >> 3

Unary

Code:

  not true

Primary

Code:

  2 * ( 3 + 2 )
