Research direction

Find the shortFmt filter implementation in the angular-filter source code, likely in a file like lib/filters/math/shortFmt.js or similar. The fix is to ensure it always returns a string by coercing numbers under 1000 to strings. Test the change by running any existing tests for shortFmt to verify the behavior.

Written by the indexing model from the issue text.

Description

The current behavior

When given an Number less than 1000, shortFmt returns a Number. Otherwise, it returns a String.

Why is this a problem?

Consider the following case:

<span>{{ (n | shortFmt:1) || 'N/A'}}</span>

When n = 0, this will print "N/A" (Why? Because 0 is a false-y value in JS. Therefore, it evaluates the right-hand side of the "||"). I believe that most developers would expect this to print "0" instead. (Similar to the behavior of angular's number filter)

Proposed fix

When n < 1000, return n + ''. This will coerce the Number into a String.

If this seems like a reasonable behavior, then I'll go ahead and create a PR for this later today.
