NumberDataField

This field class handles field of type Number.

class Person extends Model {
    static get fields() {
        return [
            'name',
            { name : 'age', type : 'number' }
        ];
    }
}

When a field is declared as a 'number', non-null values are promoted to Number type. This is seldom required, but can be useful if a field value is received as a string but should be treated as a number.
