## Validações numéricas: maior que e menor que ou igual

O mesmo se aplica para:

* `gt`: maior que (`g`reater `t`han)
* `le`: menor que ou igual (`l`ess than or `e`qual)

## Validações numéricas: valores do tipo float, maior que e menor que

Validações numéricas também funcionam para valores do tipo `float`.
