WebHOWEVER, SQL datatype "float(24)" converts to C# "float" only. So if you don't need many digits of precision and want to improve performance/memory, use float(24) in SQL and types "float" in C#. – Jason WebSep 11, 2014 · Each space equals 4 bits specifically. So, this bit representation converts directly to 32 bits, which can be represented as a single int32. To give just a little more detail: The maximum value of a space in hexadecimal is F (or 15 in decimal). The maximum value of 4 bits ( 1 nibble) is (8, 4, 2, 1) which is also 15.

WebIf it really needed to store the bits in a compacted form, you can use the BitArray type, which uses an int array internally. You can index it similarly to a normal array: var myBits = new BitArray (20); // initialize for 20 bits (1 int will be stored internally) myBits [5] = true; // similar to this: myInt = 1 << 5; Share Improve this answer lithium wheelchair battery on planeWebAug 2, 2011 · 1 Answer.
