krunner comma

SUMMARY
this is annoying. we use comma separator in currency  all the time, 100 or 1000 separator is used to make it somewhat easier to parse long currencies like in india, 
100000.56 is written as 1,00,000.00  while the same is written as 100,000.00 in american? or internationally. whatever, the point is, everytime we select a number that has comma separator, the same is treated as a fullstop, "." by the krunner and one has to manually remove commas and leave the last full stop "." as decimal separator. 
i have attached some screenshots that would explain it better


STEPS TO REPRODUCE
1.  open krunner, alt+f2.
2.  type "100,000.00" and the result should be 100000.00 but its shown as 100, treating comma as decimal separator.
3. "$100,000.00*29" and see the response.

OBSERVED RESULT
comma is treated as decimal separator forcing users to remove all commas

EXPECTED RESULT
the software is already aware of the locale but the same is not being utlized by krunner.
