Add a "digit" filter

[kechol]

How about to having a filter to convert number-like-string to digits? Angular supports "number" filter to format numbers with fraction. Maybe it is good to have a filter for opposite conversion.

{{"1,234,567"|digit}} // get 1234567

If you like it, I can send you a PR. Thanks.

A "digit" and "float" filter would be beneficial and simple to implement. Using a filter is a more elegant way opposed to exposing a parseInt/parseFloat function to scope. The concrete example I ran across was in using input[type=range] which returns a string instead of a number, where my model needed a number.

An interesting issue is that

{{ ["0", "0.5", "1.5", "2.5"] | map:parseFloat }} // should get [0, 0.5, 1.5, 2.5]

doesn't work.
