# and(?BoolExprX, ?BoolExprY, ?Bool)

Bool is the truth value of BoolExprX and BoolExprY being true.

BoolExprX
  0/1-valued expression, such as reified constraint
BoolExprY
  0/1-valued expression, such as reified constraint
Bool
  Truth value of the conjunction

## Description

Equivalent to BX #= BoolExprX, BY #= BoolExprY, Bool #= (BX+BY #= 2).

If BoolExprX and BoolExprY are constraints that have a corresponding reified form, Bool reflects the truth of both being true.
