What actually happens when you type cast? Is the variable reallocated? Which leads to my second question: Is allocation an expensive process? I heard it was...but it could be wrong. It didn't seem bad on my computer when i was doing some allocations, but thats cause i have a hyper-threading Pentium 4 at 3.4Ghz...I think, is that why unions are used rather than typecastings, which could be substituted i think.
(tell me again if im wrong).
Thats it...thank u again.
