INT <-> Binary

Does anyone have a INT to BIN and BIN to INT convertor? I thought about this, and it would be very very space efficient of a method for storing fonts (well with my method, considering my fonts use 0s and 1s without anything inbetween, including carriage returns).

except it is inefficient.
Each time, you have to divide by two. Dividing by two means that you have to divide the first digit by two, carry, second by two carry, etc. and start all over again! Insanity! Luckily for you, you lucky dog, integer division is (should be) specialized part of your chip which gets you the answer much faster than if you had done it digit by digit.

Dividing by two is replaced by SHR AX. It takes 1 cycle to execute, so it is not very slow
You can also try to optimize: DECLARE FUNCTION FastInt2Bin$ (Number&) Code: FUNCTION FastInt2Bin$ (Number&)This one doesn't make divisions

Code: St$ = HEX$(Number&)Um, yeah. ....

I don't quite understand that function much well... It looks like it only does a 4 digit binary number.
Let me explain myself a little more... My fonts can contain any amount of digits ranging from 2^2 to 48^2 (obviously not all the fonts will be squared, and the numbers might be able to go a little higher. But my point is, they will be all 0s and 1s and therefore it would be a lot more efficient if I stored them as a decimal (or hex) instead of writing all the 0s and 1s out. This format won't be easy to edit though, so it will have to be a product of another file. In the end of this miniature project, I might even have a font-editor available for you all. Though, nobody likes making fonts. Shit, I only made A and B so far (only uppercase, too). Anyways, if you could get back to me now that you understand a bit more...

Okay I modified that to be Hex to Bin, but now I need Bin to Hex... Anyone?

It worked like a charm. Thanks guys, my font method is much improved upon.

Here is the old format that I editted in notepad:
Code: . .05.08Here is the newer format which the program does recognize easily... Code: .05.08.0000000000You can see the difference in filesize... Imagine if the file was saved in binary!
