Re: How do I cast to from byte[] <-> double for making a small assembler language VM to work?

[H. S. Teoh via Digitalmars-d-learn]

Maybe use a union?

        union U {
                double d;
                byte[double.sizeof] bytes;
        }

        U u;
        u.bytes = ...;
        double d = u.d;
        ... // do something with d

        // or:
        U u;
        u.d = 3.14159;
        byte[] b = u.bytes[];
        ... // do something with b

Casting a pointer may run into alignment issues, if your byte[] isn't
aligned to a double.
