That's interesting...

Anyway, here's the real puzzle:

If you
put 1 into a
put 1 + 0 into b

Then a is a number and b is a number and a is an integer and b is an  
integer and a=b.

Split treats them differently:

split a by comma gives an array
split b by comma is still a number

So, the question is:

What's the difference between a and b?
