Enhancing Numeric Validation with Laravel's Fluent Rule Interface

Laravel introduces a more expressive approach to numeric validation through the fluent Rule::numeric() interface. This syntax transforms traditional string-based rules into chainable methods for improved readability.

The implementation provides a more developer-friendly syntax:

 1$validated = $request->validate([
 2        'name' => 'required|string|max:255',
 3        'price' => Rule::numeric()
 4                ->min(0.01)
 5                ->max(9999.99)
 6                ->decimal(2),
 7        'weight' => Rule::numeric()
 8                ->min(0)
 9                ->decimal(3)
10                ->nullable(),
11        'stock' => Rule::numeric()
12                ->integer()
13                ->min(0)
14                ->nullable(),
15        'discount_percent' => Rule::numeric()
16                ->between(0, 100)
17                ->decimal(1)
18]);
