When the number is actually 3461.49999999999999382 it should be rounded to 3461 but might be displayed as simply "3461.5".

Edit 1 in response to at least the second "edit" labeled "Edit 2" above (for sanity's sake, please stop changing the root of this conversation): 

perl -e 'print sprintf("%.20f",(3010*1.15))."\n"' # Outputs 3461.49999
+999999950000000

QED. (Now, maybe you'll go read and try to understand the stuff about floating point that was linked to quite a while ago?)
