The best solution may be to create your own custom filters and use them in combination with the native angular number filter.
app.filter('withTick', function () {
return function(input) {
return input.replace(/,/g, "'");
};
});
Implementation {{ myNumber | number | withTick }} (using the Angular number filter first will format the number with commas), after which we replace all the commas with '.
Note: the above assumes you want to put a ' character wherever a comma would be. If you're after something else (like just putting a single ' after the first character) you can manipulate and return the input as you would any javascript string.
Removing commas is similar: {{ myNumber | number:1 | noComma }} which will include the (rounded) single decimal, then you can make the noComma filter to replace all , with ''.
