# ng2-currency-mask

A very simple currency mask directive for Angular that allows using a number attribute with the ngModel. In other words, the model is a number, and not a string with a mask. You should use the version 2.x.x for Angular 2.x.x applications and the version 4.x.x for Angular 4.x.x applications.

Note: This component is ready to AoC (Ahead-of-Time) compilation.
