# Base

- `Base(int $base)`
- `Base(int $base, string $chars)`

Validate numbers in any base, even with non regular bases.

```php
v::base(2)->assert('011010001');
// Validation passes successfully

v::base(3)->assert('0120122001');
// Validation passes successfully

v::base(8)->assert('01234567520');
// Validation passes successfully

v::base(16)->assert('012a34f5675c20d');
// Validation passes successfully

v::base(2)->assert('0120122001');
// → "0120122001" must be a number in base 2
```
