Expressions

An expression is a combination of constants, variables and operators that has a single value. Here are some examples of expressions:

2.5

x + 1

arr[GetLineWidth() * 2] > 7

Conditional expressions, which have one value if a condition is true or another value if a condition is false, are handled using an If statement. It is best to enclose If statements in parentheses, because they are evaluated at the lowest precedence. If the else clause is omitted and the condition is false, the resulting value is null.
