Compact Number Formatting and Fraction Digits

[Nishit Jain]

Hi Gunnar,

Currently there is no way to obtain the below expected behavior (to get 
1K) when min fraction digit is set to non-zero value. I think that is 
not even expected when min fraction digits is set, but considering the 
objective of compact number formatting this could be a good value add to 
introduce an API which if set, truncates trailing fractional zeros while 
formatting output. This may need some thought process on its feasibility.

Regards,
Nishit Jain
