How to get the bits of a “double” as a “long”

Question

I would like to manipulate the bitwise representation of floating-point numbers in C#. BinaryWriter and BinaryReader do it this way:

public virtual unsafe void W         


        

Answer 1

You can use byte[] BitConverter.GetBytes(double) and long BitConverter.ToInt64(byte[],int) (passing 0 as the start-index), but internally IIRC these use unsafe code, plus have the overhead of an array. Pick your poison...
