# Value Sign Predicates

To check if a money amount is a credit, a debit or zero, use predicates:

* `Money.isNegative` — returns `true` only if amount is less than `0`.
* `Money.isPositive` — returns `true` only if amount is greater than `0`.
* `Money.isZero` — returns `true` only if amount is `0`.
