Using comparison expressions you can compare values of comparable types. The result is always one of the two Boolean values, true or false.
The various forms of <compare_expr> are as follows:
<compare_operand> == <compare_operand> -- equal <compare_operand> != <compare_operand> -- not equal <compare_operand> > <compare_operand> -- greater than <compare_operand> < <compare_operand> -- less than <compare_operand> >= <compare_operand> -- greater than or equal <compare_operand> <= <compare_operand> -- less than or equal
where <compare_operand> can be one of:
Comparison operations have lower precedence than math operations.
In the above examples, the sin function call and the "+" and "-" operations are performed before the comparisons.
As with math expressions, the comparison operators work on all appropriate types.
Equal "==" and not-equal "!=" operate on all types, and the relative comparisons work between comparable types.
The allowable comparison operators are documented with the value type descriptions.
