Retro and functional

Update firs - Upon upgrading to iOS11, the default bitwise of DEC/HEX conversion changed to 16bit. It can be set to 32bit by ALT MENU Settings.

Comments - Unlike other calculator apps with futuristic style, this one retros back to traditional key panel but with elegant look. I cal feel holding my old Casio calculator with more powerful functions.

Best calculator ever

but fix the bug:
171! gives 0 where 170! x 171 gives infinity

Bug needs to be fixed

0^0 is NOT 1.
But when you try this exponent operation on this program, it gives you 1. It’s a “fatal” error!
