Comment(by sprice):

 As far as I know, declaring variables in the if(){} is portable. I'm not
 sure what the speed advantage is, though. I like to explicitly give the
 compiler the opportunity to optimize, though.

 The *0.01 is to remove the divide op.

 I'm not sure where the bug is. It's been a while.
