WebApr 19, 2016 · SELECT bits & 8 = 8 FROM table; This returns a binary (1 or 0) for whether the bit in question (in this case the third) is on or off for each row in the column 'bits'. using 2^x for the xth bit instead of 8. for example, to check the 5th bit we would use 2^5 = 32 SELECT bits & 32 = 32 FROM table; However, this is needlessly complicated. phosguard in planted tank

How do I count the number of zero bits in an integer?

WebChanging the n th bit to x. Setting the n th bit to either 1 or 0 can be achieved with the following on a 2's complement C++ implementation: number ^= (-x ^ number) & (1UL << n); Bit n will be set if x is 1, and cleared if x is 0. If x has some other value, you get garbage. x = !!x will booleanize it to 0 or 1. WebNov 21, 2014 · Here's a solution that doesn't need to iterate.
