In "125 Market 125.45 Balance 87455" 87455 "seems" to be an int (in a string, OK) when 874.55 is expected.
BTW no need to be unpleasant, that will bring nothing:-) I simply try to show you where there is a problem!

Not an issue of the kata but of your code. Uou are returning int, ex:

125 Market 125.45 Balance 87455
and so on...
instead of
125 Market 125.45 Balance 874.55
...

Don't post issue unless you are absolutely sure of your code...
