Use NumberValidator for quantities, ages, prices, scores, and other numeric fields.

Create a rule

Rule::number(string $field): NumberValidator

Methods

Method	Description
min(int|float $value)	Set the inclusive lower bound.
max(int|float $value)	Set the inclusive upper bound.
length(int $min, int $max)	Configure inherited length limits when needed.
required(bool $required = true)	Mark the field as required.
optional()	Allow a missing value.
validate(mixed $value)	Return the first error or null.
validateAll(mixed $value)	Return every applicable error.

Example

use Fynix\Rule;

$validator = Rule::number('quantity')
    ->min(1)
    ->max(1000);

$errors = $validator->validateAll(0);

Bounds must be finite numbers. Non-numeric input and values outside the configured range produce validation errors.
