NAME

       findMSB - find the index of the most significant bit set to 1 in an integer

DECLARATION

       genIType findMSB(genIType value);

       genIType findMSB(genUType value);

PARAMETERS

       value
           Specifies 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.
