Subject: ruby float calculations

Could someone please explain to me why the following happens:

irb(main):001:0> 0.29 - 0.38 + 0.1
=> 0.00999999999999998
irb(main):002:0> 0.29 + (-0.38 + 0.1)
=> 0.00999999999999995
irb(main):003:0> 0.29 + 0.1 - 0.38
=> 0.01

How can I prevent something like this from happening, or at the very 
least how can I work around such errors?

Many thanks in advance.
