findMSB - find the index of the most significant bit set to 1 in an integerDECLARATION¶
genIType
findMSB(genIType value);
genIType
findMSB(genUType value);
PARAMETERS¶
valueSpecifies the value whose bits to scan.
DESCRIPTION¶
findMSB returns the bit number of the most significant bit that is set to 1 in the binary representation of value. For positive integers, the result will be the bit number of the most significant bit that is set to 1. For negative integers, the result will be the bit number of the most significant bit set to 0. For a value of zero or negative 1, -1 will be returned.VERSION SUPPORT¶
