Efficient Algorithm for Bit Reversal (from MSB->LSB to LSB->MSB) in C
...bits of v; first get LSB of v
int s = sizeof(v) * CHAR_BIT - 1; // extra shift needed at end
for (v >>= 1; v; v >>= 1)
{
r <<= 1;
r |= v & 1;
s--;
}
r <<= s; // shift when v's highest bits are zero

...ent, I have revised my original statement. He is correct, there will be a difference in performance between an inline table valued function (ITVF) and a multi-statement table valued function (MSTVF) even if they both simply execute a SELECT statement. SQL Server will treat an ITVF somewhat like a VI...
