This is handy. Could you add octal support?

the hex number C4E70B40A5324D02BB5F4978537276DE
when converted to decimal through your tool shows
261728335976398933936745925771024037598 where as if i convert using BigInteger in c# converts it to -78554030944539529526628681660744173858 ?? :(

@Chandra, you will need to specify unsigned biginteger in C#, as without specifying, it assumes it to be signed.

Hallo!
We have to calculate big dec number (40char) from big hex naumber (32char) in our xBase (32bit) application. Is exists a funcion on form, we can use it (obj, dll)?

In all respects, Metod

Really useful utility, not many converters go large enough :)

I am using OpenSSL library in ObjC. When I am creating EC Private key, I get x, y values in BigNum whose hex representation is
Q(x, y): (4BEE6F8C0AD800047C0E4DD27B7C68A0B51D4DC13367781BBB82B50F6BD0E6CF, 60293ED859F44A392C8A9E2C6570CECB60FCE2C1988B48E33B0D218C1353D53A)

Now when I am converting it to Base64URLEncoded, the output is
x = S-5vjArYAAR8Dk3Se3xooLUdTcEzZ3gbu4K1D2vQ5s8
y = YCk-2Fn0Sjksip4sZXDOy2D84sGYi0jjOw0hjBNT1To

whereas your website shows:
x = 4lkRumAs004V0vDqdjyQA2r7Kt1CsTu6xk2jGzhqERF
y = 60fFjXPz4evB8gUB6LmpijW=EB1c8j8upiD8OmJKzKw

Please suggest.
