_BitScanForward( &index, *digits ) ;
From the documentation:
|If no bit is found, the function returns 0 and the value
|written to the address in the first parameter is undefined.
. However, if there are 32 0s before a 1 is found, this
might be intended to add "32" to the total zero count.
(GCC's and Clang's "__builtin_ctz" can also count bits and
might be more portable.)
