How to format numbers in underscore template?
formatting, underscore.js, underscore.js-templating
Solution
Just use `Number.prototype.toFixed()`:
`<%= a %> div <%= b %> is <%= (a/b).toFixed(2) %>`
var tpl, content;
tpl = $('#division-tpl').html();
content = _.template(tpl)({a: 10, b: 3, digits: 2});
$('#content').html(content);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.0/jquery.min.js"></script>
<script src="//cdnjs.cloudflare.com/ajax/libs/underscore.js/1.7.0/underscore-min.js"></script>
<script type="text/template" id="division-tpl">
<%= a %> div <%= b %> is <%= (a/b).toFixed(digits) %>
</script>
<div id="content"></div>
Problem
I have an expression in my underscore template like this: ``` '<%= a %> div <%= b %> is <%= a/b %>' ``` I would like to limit the number of decimal counts to a specific number. Is it possible in underscore.js? Expected: ``` '10 div 3 is 3.33' ``` but actually I see: ``` '10 div 3 is 3.333333333' ```
