Binary number support

[xvxx]

It would be nice if LDPL could work with binary data. It would probably need two things:

1. Support for binary (0b1010) and hex (0xFF) number literals.
2. Support for bit operations.

Maybe the commands could look like this:

• BITWISE A AND B IN C
• BITWISE A OR B IN C
• BITWISE A XOR B IN C
• BITWISE NOT A IN C
• BITWISE SHIFT A LEFT BY B IN C
• BITWISE SHIFT A RIGHT BY B IN C
• GET BIT AT N FROM A IN C

Would this be a good candidate for the language or should it be an extension?

I think this would be a great addition to the language! We can even add the symbols <, >, |, &, ¬ to represent shift left, right, or, and and not to solve math without changing almost anything of the current code!

I think solve math will take some work because C/C++ doesn't allow bitwise on floating point numbers.

So for the normal statements, we probably have to: 1. check if there's a fraction, 2. convert to int if no fraction (error if so), 3. perform bitwise operation, 4. convert back to float. This is how Lua does it according to manual section 3.4.3, since Lua also only has a single number type as far as the programmer is concerned.

However, if we add a sibling to solve math and name it something like solve bitwise, we can convert all input to int first. So maybe something like: IN var SOLVE BIT a | b

Oh right, we are using floating point numbers... I didn't think about that. I like what you are saying though. There's no real need to add it to solve math so don't really mind that.

@dvkt should I close this? I don't really think that we'll end up using this in LDPL an in any case we could implement it as part of the standard library.
