Typecasting Resources

Also, with integer arithmetic the order the operations are specified can how a profound impact on the result. Understanding these topics is required to understand why most of the casting that is needed to program the FIRST RC is necessary.

That sums it up pretty well. I plan on creating a resource to spread the understanding of this issue. It is mentioned sporadically, but never really explained in the FIRST documents that I have browsed...

Please post more info/examples on this topic if you can!
