Sorry, but do you want to tell me that there is a difference between manually entered 142217,495 and the same value as a result of currency conversion 
? Your post: Re: Rounding off the value with only logic script
2. What do you mean ? - I mean rounding script text you execute in UJKT! Show it! I am not sure it's correct! And better a screenshot of UJKT with this script!
As I already posted I have performed all the tests and found no issues. Currency conversion and rounding are performed correctly...
