How to parse signed zero in C#?

In C#, signed zero can be represented using the System.Double or System.Single data types. Signed zero has a bit pattern where the sign bit is set to 1 and all other bits are set to 0.

To parse signed zero in C#, you can use the System.BitConverter class to convert a byte array representation of signed zero into a double or float value. Here's an example:

byte[] bytes = new byte[] { 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; double signedZero = BitConverter.ToDouble(bytes, 0); Console.WriteLine(signedZero); // prints -0.0

In this example, the byte array { 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 } represents signed zero. The BitConverter.ToDouble method is used to convert this byte array into a double value.

Note that signed zero is a rare edge case and is typically not used in most applications.
