Angular PrimeNG Form InputNumber Decimal Mode Component

Angular PrimeNG is an open-source framework with a rich set of native Angular UI components that are used for great styling and this framework is used to make responsive websites with very much ease. In this article, we will learn how to use the Form InputNumber Decimal Mode Component in Angular PrimeNG.
