Returns the bit position of the lowest bit set in a 64-bit value.
This function computes the bit position of the lowest bit set in the 64-bit value specified by Operand. If Operand is zero, then -1 is returned. Otherwise, a value between 0 and 63 is returned.
Operand | The 64-bit operand to evaluate. |
0..63 | The lowest bit set in Operand was found. | |
-1 | Operand is zero. |
