Assume this constraint verifier code:

constraintVerifier.verifyThat(TennisConstraintProvider::fairAssignmentCountPerTeam)
        .given(assignment1, assignment2, assignment3)
        .penalizesBy(BigDecimal.valueOf(1.732));

The test will pass regardless of whether the constraint actually impacts by 1.732, 1.73 or 1.7. This is because internally, the impacts are actually cast to long.
