Limiting the Decimal to 2 digits

[Dinesh P.R.]

I am running a small expression in angularjs as shown in the code below

<span class="badge badge-success">{{((medicine.MRP-medicine.SRATE)*100)/medicine.SRATE}}  %</span>

I am trying to find the percentage of  profit in selling a medicine.

I want to limit the number of decimals in the percentage to 2.  Do we have any angular modules to limit the decimals?

Thanks

You could write a filter that returns the substring 2 digits after the period in the double.

Unfortunately, docs.angularjs.org is down..  but this works: https://github.com/angular/angular.js/blob/master/src/ng/filter/filters.js#L54

{{myNumber | number:2}} takes it to two decimals

[Will Kriski]

http://docs.angularjs.org/api/ng.filter:number should work

Thank you all, number filter worked very well

Reviving and old thread but the number filter has an odd behavior. When not specifying the number of decimals {{myNumber | number}}, angular format with up to 3 decimals:

• 123.4567 gets formatted as 123.457
• 123 gets formatted as 123 (no decimals shown)
  

However, when specifying the number of decimals {{myNumber | number:2}}, angular forces them to appear even for integers:

• 123.4567 gets formatted as 123.46
  
• 123 gets formatted as 123.00
  

Is there a way to set the maximum number of decimals so that 123 would still appear as 123 without writing a custom filter?

Thanks,

Christophe

You can chain two number filters like this:
{{ myNumber | number:2 | number }}

[Ciprian Serbu]

actually chaining won't work if the number is greater or equal to 1000 as the first filter will add one or more commas and the number filter does not know how to parse numbers with commas, e.g. $filter('number')('1,000') returns an empty string

you could try calculating the number of digits yourself and passing it to the filter: $filter('number')(x, Math.min(String(x).split('.')[1] || 0, 2))

You could extend the pipe and make you're own. This is probably the best way to get the exact format you want.
