Review request for KDE Frameworks, KDE Utils, John Layt, and Evan Teran.


Repository: kcalc


Description
-------

To remove the last bits of KDELibs4Support in kcalc port, I had to replace KLocale::formatNumber() with a custom function, because I found no way to format arbitrary precision numbers with QLocale.

The groupSize is hardcoded to 3, I did not find  a simple way to query QLocale.

The code also replaces all digits with locale digits; not sure if the original KLocale code did the same and if this should be applied to kcalc.

Testing
-------

Tested with german locale, which has '.' as groupSeperator, and ',' as decimalPoint.


Thanks,

Christoph Feck
