hi,
    that was good to know

   irb(main):001:0> o=10.0000000000000001
=> 10.0
irb(main):002:0> o.class
=> Float
irb(main):003:0> 10.0000000000000001.class
=> Float
irb(main):004:0> 10.00000000000000000000000000000000000000000000000001.class
=> Float
irb(main):005:0> 10.00000000000000000000000000000000000000000000000001
=> 10.0
irb(main):008:0>
10.6856856856856856856755555555555555555555555555555555555551
=> 10.6856856856857
irb(main):009:0>
10.6856856856856156856755555555555555555555555555555555555551
=> 10.6856856856856
irb(main):010:0>

never thought what happens when floats get this way "
10.00000000000000000000000000000000000000000000000001"
