I realize this thread is a little old by now, but anyways...
What's the smallest program you can make that gets a decimal number and converts it to a 1-byte binary?

I backed up his site, I'll check it, give me a sec'.
EDIT: He has this (closest thing I see):
[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]
PROGRAM:BASECONV
int(round(BfPart(NB^seq(I,I,?int(ln(N)/ln(B))-1,?1
Returns a list containing the digits of N in base B.
Limitations/Known Issues
Fails for inputs less than 1 for N and less than 2 for B.
Other Notes
To specify a dimension, change the begin argument to ?value.

[font="courier new;font-size:9pt;line-height:100%;color:darkblue"]int(round(2fPart(N2^seq(I,I,‾int(ln(N)/ln(2))-1,‾1
found it. N is the decimal number

| Hmm...Perfect. Do you know if it's legal to use the routine in a program (that I'm going to distribute) without infringing the copyright? |

Shh....his routine gives you {0,0,0,0,0} or something along those lines when you enter 16. I made my own  |

| I'd replace the -int() with -int(round()) if it's what I'm thinking. |

The only thing I need to know now is how many possible 5-digit binary combinations are there?
I'm guessing 2^5, which is 32, but I get the weird feeling there's more. |

2^4+2^3+2^2+2^1+2^0=32
Well, it gives a number of 0-31 (zero is a number), and a signed value of -15 to +15.
Meguesses it's for ASM programming...
[Edit: It may be giving out lists either because of what Darkerline said or because you cannot represent a base-16 number with 1 digit in a decimal system. Or it's because I don't know what that code does (I don't love seq())

yes you can. 9 in hexidecimal is 9 in decimal |
