Hello all,
This is my first mail into the mailing list, so please be kind with any
errors, and please point them out so we can learn from them :)
Last night I was messing with some simple arithmetic operations in irb, and
notice a funny thing: when I made subtractions (did not tested any other
operation) I did not got the expected results...
It seems that the result of floating-point subtraction is not correct... as
if it had some residual value left in some deep decimal position...

ruby 1.9.2p180 (2011-02-18 revision 30909) [i686-linux]
I'm I missing something?
Or is it that the results are in fact incorrect and a bug should be
reported?
If so, should I report the bug into "http://redmine.ruby-lang.org/
", or where?
Thanks in advance, Zipizap
