How about
uint64_t a = 348659235483;
uint64_t result = (a & 0x0fe0) >> 6;
Pergunta
I want to do a simple bit mask operation. Lets say
uint64_t a = 348659235483;
Assuming this number is converted to binary, I want to extract the values from bit 6 to 12 (0 is MSB on the right end). What is the smallest code for that?
the binary is
10100010010110110110101101/110101/0011011
So I want to save 110101
which is 53
