# #\=(?Expr1, ?Expr2, ?Bool)

Reified arithmetic comparison

Expr1
  An arithmetic expression
Expr2
  An arithmetic expression
Bool
  Variable, 0 or 1

## Description

Reified version of #\=/2, i.e. the truth value of the comparison is reflected in the value of the 0/1 variable Bool.

This constraint suspends until its first two arguments are ground. It then unifies Bool according to the truth value of the corresponding #\=/2 constraint.

### Modules

This predicate is sensitive to its module context (tool predicate, see @/2).

### Exceptions

(24) number expected
  Expr1 or Expr2 is not an arithmetic expression.
