Answer 1

Just think about it
Let's say you have a number 10
10 % 5 = 2
10 % 2 = 5
10 % 1 = 10
10 % 0.5 = 20
10 % 0.1 = 100
10 % 0.00...001 = 10^n times 0
I hope you understand.

Answer 2

Because the designers decided not to throw an exception in this case.

Answer 3

Ok... but it's a bit "illegal"...
