Relational operators (binary)

The binary relational operators are =, ==, !=, <>, <, <=, >, and >=.

Syntax

  Equal:                 
  <operand> =  <operand>

                         
  <operand> == <operand>

  Not equal:             
  <operand> != <operand>

                         <operand> <> <operand>

  Less than:             <operand> <  <operand>

  Less than or equal:    
  <operand> <= <operand>

  Greater than:          
  <operand> >  <operand>

  Greater than or equal: 
  <operand> >= <operand>

Description

These operators compare two operands and return 1 if the condition is true or 0 if the condition is false.

The operands can be any expression evaluating to an absolute expression.

Example

See the following listing for an example of the binary relational operators

Listing: Binary relational operators


3 >= 4      ; = 0  (FALSE)
label = 4   ; = 1  (TRUE) if label is 4, 0 or (FALSE) otherwise.

9 <  $B     ; = 1  (TRUE)
