38<H2>Description</H2>
39<P>Fast converts an unsigned 8-bit integer into a 32-bit floating value in two cycles (using a load and store).</P>
40<P>Be aware that the <A href="OSInitFastCast.html"><CODE>OSInitFastCast</CODE></A> function must be called prior to invoking this function.</P>
41<P>In the standard debug builds, this function and all other fast cast functions will not be inline-expanded.</P>
42<P>This function takes addresses as arguments to load/store instructions.&nbsp;Taking addresses as arguments ensures that the compiler will reserve space on the stack (rather than forcing the programmer or the inline function to allocate space). The stack-allocated variables will likely be in the cache.</P>
