Software Engineering lesson 7:

"Greater than or equal to" is not the same operation as "Greater than" with a slightly different value (for floating point numbers). More specifically, if I have the statement "ColumnA is valid if it is greater than or equal to 150", it should not be implemented as "ColumnA > 149.9".

Heh. I found something, in looking over the code this week.
The long and the short of it:

unsigned int count = 640
[...]
while( count >= 0 ){...}

Please, please cry with me.

Clearly, the author of that code intended it to be stopped by the exception thrown when the int overflows.
