| // Based in http://stackoverflow.com/a/2686098/4436816 | |
| // | |
| // Usage examples: | |
| // {{ 2134124 | abbreviate:2}} -> 2.13M | |
| // {{ 2134124 | abbreviate }} -> 2M | |
| // {{ 1000 | abbreviate }} -> 1K | |
| myApp.filter('abbreviate', function() { | |
| return function(number, decPlaces) { | |
| // 2 decimal places => 100, 3 => 1000, etc | |
| decPlaces = Math.pow(10,decPlaces || 0); | |
| // Enumerate number abbreviations | |
| var abbrev = [ 'K', 'M', 'B', 'T' ]; | |
| // Go through the array backwards, so we do the largest first | |
| for (var i=abbrev.length-1; i>=0; i--) { | |
| // Convert array index to '1000', '1000000', etc | |
| var size = Math.pow(10,(i+1)*3); | |
| // If the number is bigger or equal do the abbreviation | |
| if(size <= number) { | |
| // Here, we multiply by decPlaces, round, and then divide by decPlaces. | |
| // This gives us nice rounding to a particular decimal place. | |
| number = Math.round(number*decPlaces/size)/decPlaces; | |
| // Handle special case where we round up to the next abbreviation | |
| if((number === 1000) && (i < abbrev.length - 1)) { | |
| number = 1; | |
| i++; | |
| } | |
| // Add the letter for the abbreviation | |
| number += abbrev[i]; | |
| // We are done... stop | |
| break; | |
| } | |
| } | |
| return number; | |
