    Operators

    Expressions can be combined using operators. Each operator as a precedence priority. Here is the list of those expression's priority.
    • primary
    • unary
    • power
    • multiplicative
    • additive
    • relational
    • logical

    Logical

    These operators can do some logical comparison between other expressions:
    • or, ||
    • and, &&

    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
    • !, not, -, ~ (bitwise not)
    Code:
      not true
    Primary
    • (, )
    • [values]

    Code:
      2 * ( 3 + 2 )
