What's the document number you're using?

rafaelbpa commented 6 years ago

I am using CPF.valid?(777), for example. This should return false, am I right? But is returning nil.

This should return false, am I right?

No, you're not. Predicate methods are not required to return booleans. nil is a falsy value, so all you have to do is not checking for data type. If type is important to you, you can coerce it in your code like !!CPF.valid?(777).

Worked for me. Thank you, Fernando!
