angular format 2 digits ng-value

Question

I'm a newbie on angularJS.

I want to divide 2 numbers, but I want to round the result with two digits.

I try many things :

<input type="number" ng-model="var3" ng-value="var3 = Math.round((var1/var2)*100)/100" />

<input type="number" ng-model="var3" ng-value="var3 = (var1/var2).toFixed(2)" />

Do you have any ideas ?

if var3 is always equal to var1/var2 why do you want to have input for it? just display it as text — Dmitry Pavliv

I display it because the user want to see the value before submitting form. — Samuel Dauzon

Your toFixed() example would work with 1 minor change, Angular returns a string, change the input type to text. I would also suggest changing the input to disabled that way the user knows it will be submitted but they aren't allowed to change the value. — jnthnjns

Not sure how to do it with ng-model and ng-value but this filter works fine:

<input type="number" value="{{ var3=var1/var2 | number:2 }}" />
