# BoolVal

- `BoolVal()`

Validates if the input results in a boolean value:

v::boolVal()->isValid('on'); // true
v::boolVal()->isValid('off'); // true
v::boolVal()->isValid('yes'); // true
v::boolVal()->isValid('no'); // true
v::boolVal()->isValid(1); // true
v::boolVal()->isValid(0); // true
```
