|Re: Support of binary and hexadecimal integers in PARI/GP|

Ok. Will deliver tomorrow.

No, it's for master - i.e. trunk.
I'm new to git - work mostly w/ perforce and svn

Hm, could you point me to the test which fails?

Hm, silent failure in basecase and something useful w/ my changes.
Looks like my change is better :)
But anyways, provided I have existing test case at hands I'll try to mitigate it.
>Currently, GP printf can print in hexadecimal and octal but not in binary.
But, my change goes beyond this.
If default base is changed to hex, ALL integer values are printed in hex.
I.e. Mod(20,33) will look like Mod(0x14,0x21)
To me, it's really useful when I use GP as a fancy programmer's calculator.
I play with bignum arithmetic in my spare time. And for debugging I often do calculations in GP.
I use custom functions to convert between dec and hex and it's always a pain.
Getting all results in desired base is much better.
That's why I propose this patch.
