ng-pattern only work in angular 1.2.1, but not on 1.3.17, 1.4.3 and 1.4.4

Hello, I have a problem, I trying to validate an input number, setting 00.00. what I need?, only two digits after and before decimal dot, no matter if the two digits after decimal dot are 00.

Between many patterns, I found this that it serves me:
/^\d{0,1}(\d.\d)?\d?$/

I created four examples on plunker with different versions of angularjs, that explain my problem and no matter if set pattern instead ng-pattern attribute, still not working.

Angularjs 1.4.4 http://plnkr.co/edit/K00ffy?p=preview
Angularjs 1.4.3 http://plnkr.co/edit/jCYj97?p=preview
Angularjs 1.3.17 http://plnkr.co/edit/93absW?p=preview
Angularjs 1.2.1 http://plnkr.co/edit/ooFneS?p=preview

The last one works, but my question or the question is, what it's wrong?, me or the versions of AngularJS?.

Thank you.

It has to do with the way angular is handling the input -- After your 1.2.1 example the input fed into the pattern validator is a number type instead of a string. Thus, when it's 00000.000000000 it's passed into the validator as 0 then cast to the string "0".

There was a pretty heavy refactor in 1.3 that appears to have added the $parser to the inputDirective which is what is causing your woes.

Thanks for opening the issue. It's being tracked here already: #12344

@pokaxperia the fix is the above patch, which you will have to wait on the release of. In the interim, you can get regex matching from a text field
