Ionic/HTML5 - Decimal Keyboard Input?

How do I display a numeric keyboard with a decimal button on iOS and Android? Is there an Ionic-specific way to do this?

I'm able to display a numeric keyboard on both iOS and Android with the following:

<input type="number" pattern="[0-9]*">

iOS appears to disregard the type of value "number" and displays the number pad based off the pattern attribute, but the type is set to "number" anyway for Android.

Edit: Forgot to mention that I have tried pattern="[0-9.]*". iOS simply shows the full keyboard when I do this.

Edit2: I've also tried pattern="\d+[,.]?\d*" - again, to no avail.
