# Decimal

- `Decimal(int $decimals)`

Validates whether the input matches the expected number of decimals.

```php
v::decimals(2)->isValid('27990.50'); // true
v::decimals(1)->isValid('27990.50'); // false
v::decimal(1)->isValid(1.5); // true

```

## Known limitations

When validating float types, it is not possible to determine the amount of
ending zeros and because of that, validations like the ones below will pass.

```php
v::decimal(1)->isValid(1.50); // true
```
