Float conversion in ruby

Question

I'm starting Ruby and I saw that we have an automatic conversion.
After writting a small programm it get me this:
a=3
a+=0.3
puts a
a+=0.3
puts a
I get as a result 3.59999999996
Is there a reason why the addition between floats isn't working as intended?
Thx in advance
