Gold star for Tres ;)
In this case, I believe the variable step is a float which is between 0
and 1 (noninclusive), which would mean that the loop would run forever
(since it's rounded to 0 before getting added to the int). It's been
ages since I've touched any C# code so I don't remember if C# has some
implicit conversion weirdness which would allow the loop to function as
intended, but in C/C++ it definitely doesn't work.
