u32 MATH_MSB( u32 x );
| x | The value to scan |
Returns the highest order bit set to 1.
This function looks for the highest order bit that is set to 1 when x is expressed as a binary 32-bit value. 10(01010b) is 8(01000b), and 0 is 0.
MATH_MSB is another name for the MATH_GetMostSignificantBit function.
The lowest-order bit set to 1 can be found with the MATH_GetLeastSignificantBit function.
