WebDec 28, 2016 · To shift an m bit integer by c bits, I would need at most c bit operations. To expand, shifting right by c bits, is deleting the c most significant bits. Shifting left by c bits, is simply adding c trailing 0s, so all in all c operations. I guess the time complexity of shifting is O ( c) then. – Tobi Alafin. Webbecause negative number is stored in 2's complement form in the memory. consider integer takes 16 bit. therefore -1 = 1111 1111 1111 1111 so right shifting any number of bit would give same result. as 1 will be inserted in the begining.

WebShifting is much faster than division. It may be that the author of the C code did optimize the division/multiplication because shifting does the same as dividing/multiplying by 2 (or by powers of 2) but is faster about 100 times on most of the CPUs. But in most modern C compilers this optimization is done by compiler itself. Share Webor by testing the sign bit: uint16 a = original; bool negative = a & 0x8000; Testing the sign bit can also be done on some platforms with a left-shift operation, if the operation produces a carry. uint16 a = original; a = a << 1; // Binary left-shift by 1 bool carry = /* save carry from this calculation*/; bool negative = carry; WebBinary numbers are multiplied and divided through a process called shifting.
