 #### Custom Format Strings
 
-The `fmt` argument accepts a [Unicode number pattern](https://unicode.org/reports/tr35/tr35-numbers.html#Number_Format_Patterns) string (the same syntax used by [Babel](https://babel.pocoo.org/en/latest/numbers.html)). When `fmt` is provided it takes complete priority over the `decimal_places`, `max_decimal_places`, `min_digits`, and `separator` arguments — those arguments are silently ignored.

 The `integer` and `multiplier` arguments **are** still applied to the number before the format string is used.
