It is almost done, but I thought I share the project with you.
Basically, it is a byte converter. But it isn't like the ones I saw on ticalc.org when I searched. It supports bits, nybbles (yes, there is such a thing), bytes, kilobytes, megabytes, gigabytes, and terabytes. The only bad part is that it is not optimized. It is because it isn't my first programming language, and it would drive me crazy if I forgot to use a closing parenthesis or quote. I'm sure using lowercase in a couple of spots isn't helping either.
If it takes off, then I will release a second version, one that supports the standard sizes (16, 32, 64) for word, dword, and qword.
To anyone who actually cares: I will not support anything like Kibibytes (KiB), ever. The IEC has approved this standard 8 or 10 years ago, and no-one has really caught on. Not Microsoft, not Apple, not Linux. I use 1024 for the conversions, like the IEC standard specifies, not 1000, which is what a lot of people are used to. If you need to use the 1000 conversion technique, this is not for you.
