Convert Hex to Double

Question

how do you set specific bits for a double?

For an int I\'d do something like this:

public static int Value { get { return 0xfff8; } }

Answer 1

Look at the BitConverter class or go unsafe.

Unsafe example (untested):

public unsafe double FromLong(long x)
{
  return *((double*)&x);
}

BitConverter example:

double d = BitConverter.Int64BitsToDouble(0xdeadbeef);
