<= _ _ _ LEQSIGN _ _ _ _ _ _ _ _ _ _ _ _ operator

<= is an infix binary comparison operator that returns true if its first argument is less than or equal to its second argument.

syntax:

<expression> <= <expression>

<expression> must evaluate to a number, e.g., integer, rational or floating point number.

examples: 


a := 10; 

  A := 10 


if a <= 10 then true; 

  true

The binary comparison operators can only be used for comparisons b etween numbers or variables that evaluate to numbers. The truth values returned by such a comparison can only be used inside programming constructs, such as if...then...else or repeat...until or while...do.
