Last active August 2, 2018 12:41
Angular filter to abbreviate large numbers, optionally receiving the number of decimal places as parameter.
// Based in http://stackoverflow.com/a/2686098/4436816

// Usage examples:
// {{ 2134124 | abbreviate:2}} -> 2.13M
// {{ 2134124 | abbreviate }} -> 2M
// {{ 1000 | abbreviate }} -> 1K
