    I use this as a quick handy tool during programming. I would suggest to show the leading zero's in hex and binary (in portrait mode). They're shown in landscape mode. It's a bit misleading when leading zero are not displayed.

    Great app, easy to navigate to the functions. I would like to have multiple memory locations. All conversions included are a big help for me. Keep up the good work!

    Hi there, I was thinking the gcd(x,y) and z^y Mod x functions would be great additions to this calculator. These functions are really simple, but super powerful for programmers and mathematicians. Also a programmable mode would be awesome. Perhaps somethi

    I got this mainly as a programmer's calculator, but was very pleased to find that it also does a great many unit conversions. Excellent all round.

    One the best RPN calc. Slow a little bit, but very useful. Programmer mode is nice.
