Awesome app, with a simple layout, I work in PC firmware and often need to convert between hex, decimal, and binary so I've been searching for this for a long time.
I've found a bug, though. When I am in hex, 8bit mode, I'm unable to enter values > 0x7F. I get a toast message saying "Value rejected, is bigger than Bit length allows. Same general principle applies to hex, 16bit mode; I can't enter values > 0x7FF.

@jerdog: APK is now in Post 2 attached.

@jjohns63: You are right, in HEX and Bin You should be able to do that. Only in Decimal this should not be allowed if you have a signed value. Will fix this in next release. Happy that you like it

Is it possible to get option to display BIN from left to right, this will come in real handy for dip switch addressing hardwares.

@sleepyfu: You mean Little and Big Endian or do you mean completely Reverse?
E.g. Dec 2400 = Bin 0000 1001 0110 0000
What would you display?

Cheers

I'd love to see more bases supported like base 12 or base 20
(or theoretically support for all base systems with brackets for each digit if it is larger than 10)
in a future release

Reverse as 1=1000, 2=0100, 3=1100, 12=0011, Thanks!
Reason being most hardware I have seen with binary address using dip switches has 1 on the far left.
