Steps to Reproduce

<decimalbox format="locale:en-IN" cols="20" value="123456789.00"/>
<doublebox format="locale:en-IN" cols="20" value="123456789.00"/>

Current Result

the fractional part is removed, it shows 123456789

Expected Result

a way to specify how many fractional digits to show

Debug Information

• the requirement is like format="#,##,##0.00", 2 fraction digits
• maximumFractionDigits and minimumFractionDigits can achieve
• Although this is a bug, it's more like a missing specification of the feature locale-dependent format. We should list the spec before implementing it.

Workaround

c:fractionDigits="2" in 15083.zul + decimal_fraction.js
