Dear list,

My question is surely outside the scope of Erlang, but I thought I’d ask it here as it is the language I will use, and I am sure you guys have experience in the domain of numbers.

I understand Erlang uses the IEEE-754 specs for floating-point numbers arithmetic. So when I type in the console:

1> 0.2 + 0.1.

This is fine, I was expecting that. However, why the following works:

2> 0.1.

Is it because of some rounding behaviour?
