Long time since I've touched TI-BASIC again (yes, Axe is that addicting Grin). I made a quick program that's becoming really useful for ASM: a program that calculates anything in binary, octal, decimal, hex, or any combination of the four. In other words, type in something like "b10110101+o571-x1E+241" and it'll output the answer as 769. Since it calculates using the expr( command, you can put literally any numerical expression in and it'll solve correctly, including exponents, trig, and other functions. Shot below Smiley

EDIT: New version uses all uppercase letters. Also, I changed hex to H. In other words, replace b with B, o with O, and x with H.

EDIT2: Even newer version changes it back -- sorry.

And so far, it's a nice, reasonable 295 bytes.

Anyone who finds any optimizations, feel free to post it!

does it take into account the base? like if i put in b0012, would it tell me that 2 won't work? or would it just calculate it as 4?

It would actually calculate it as 22. Kinda weird, but let me explain:

All the program does is convert numbers of other bases to decimal for the OS to resolve. It uses a While loop for each number to detect when the number ends. In this case, the program knows that the number ends at that 2. So it inserts 2 into the final equation instead of b001, and it becomes 22.

I'm probably gonna change this. I've already decided what I'm going to do: I'm going to add parentheses around the number to be inserted, so that it becomes b0012=(b001)2=(2)2=4.

but what if the user mistypes b0011 into b0012? you mean your program will just convert this into 2*b001? then that begs the question, what if you have a string like b10201012? wouldn't your program mark it as 2*(b10) + 1012? i'd suggest getting the program to recognize that the given amount exceeds that of the maximum number possible, and then telling the user. regardless, it's a great program if you put in what you meant to (:

Hmm, good point. It would add ~50 bytes and make each pass a lot slower, though Sad

Anyway, story behind the program:

It was horrible.

I'd made a program that I thought was brilliant (or at least very, very useful Grin). I wanted to share it on Omni, but (1) I lost my link cable; (2) WabbitEmu's Export feature was broken; and (3) SourceCoder still had bugs, which gave the program random syntax errors.

So I made the program with SourceCoder and started debugging it with Wabbit. Then I realized that even if I fixed it, I couldn't export it. So I opened up a hex editor (yes, on the comp, and yes, I'm suicidal, apparently). And so I began the task of individually editing hex codes to make it work.

That's when I got BSoD'd. It was horrible.

Thanks, and I just realized something: It works almost the same way as Calcalca. Maybe I could combine them...

Mhmm idk. Calcalca is more math-oriented. Programmers might prefer to just have the base conversion to save as much space as possible. In my case I haven't needed math programs since the last time I had maths was 7 years ago Grin

Good point. Well, I'll change it a bit, add a readme, and hopefully release this tomorrow Smiley

A question: Would people rather use lowercase letters for binary, octal, and hex at the cost of having an extra ASM sub, or just use uppercase?
