True enough however, this was a question regarding the Keil tools and I figured a more efficient method was available so I suggested it.

Bryan's approach - using a union - might be quicker, but requires you to <b>know</b> the Compiler's byte ordering; it may not be portable to a different compiler or different processor.

Thomas' approach looks like trying to emulate the action of a union; it'd be simpler (probably also more efficient) to just use a union!
