ng2-currency-mask

This is a fork of ng2-currency-mask that solves browser autocomplete issue.

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. It was tested in Angular version 13.

14    imports: [
15        ...
16        CurrencyMaskModule

Validation

This directive also provides built-in validation for minimum and maximum values. If the attributes 'min' and / or 'max' are set, the Angular CSS class 'ng-invalid' will be added to the input to indicate an invalid value.

1<input currencyMask [(ngModel)]="value" min="-10.50" max="100.75" />
