Numeric Expressions

A base numerical expression can be either a constant, variable, or another numerical expression enclosed in parentheses. The five types used (addition, subtraction, multiplication, division, and exponentiation) are listed below. When evaluating an expression exceeding the maximum or minimum values at any point creates an undefined result. (maximum value: 2,147,487,647; minimum value: -2,147,483,648)
Floating point is not supported.
When using division, the number is always rounded down. For example, 5/2=2. Use
MOD
 to determine the remainder.

Format

  1. + (addition) Addition expressions use this format:
    <A>+<B>
    5+2 result = 7
    VAL ("25") +2 result =27
  2. – (subtraction) Subtraction expressions use this format:
    <A>-<B>
    5-2 result = 3
    VAL ("25") -2 result =23
  3. * (multiplication) Multiplication expressions use this format:
    <A>*<B>
    5*2 result = 10
    VAL ("25") *2 result =50
  4. / (division) Division expressions use this format:
    <A>/<B>
    5/2 result = 2
    VAL ("25") /2 result =12
  5. ^ (exponentiation) Exponentiation expressions use this format:
    <A>^<B>
    5^2 result = 25
    VAL ("25") ^2 result =625
