# Relational operators

All relational operators compare the values of the operands and return True (-1) or False (0) as the result. All relational operators are binary.

 < Less than A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. <= Less than or equal A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. > Greater than A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. >= Greater than or equal A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. = Equals A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. <> Not equivalent to A numeric comparison is made if both operands can be interpreted numerically. The operation returns the logical value of the evaluation of the comparison. precedes Unlike the < operator no attempt is made to make a numeric interpretation of the argument values before the comparison. The operation returns true if the value to the left of the operator has a text representation which, in string comparison, comes before the text representation of the value on the right. Example:  '1 ' precedes ' 2' returns FALSEwhilst' 1' precedes ' 2' returns TRUEas the ASCII value of a space (' ') is of less value than the ASCII value of a number.Compare this to:'1 ' < ' 2' returns TRUEand' 1' < ' 2' returns TRUE follows Unlike the > operator no attempt is made to make a numeric interpretation of the argument values before the comparison. The operation returns true if the value to the left of the operator has a text representation which, in string comparison, comes after the text representation of the value on the right. Example:  ' 2' follows '1 ' returns FALSEwhilst' 2' follows ' 1' returns TRUEas the ASCII value of a space (' ') is of less value than the ASCII value of a number.Compare this to:' 2' > ' 1' returns TRUEand' 2' > '1 ' returns TRUE
