Best of all, it operates in Standard or Reverse Polish Notation modes, complete with a multi-line stack display! If you have an iPad, you also get the Scratch Pad, which is a neat way to work with stack values using your fingers.

In addition to the usual hexadecimal and binary base conversion, it features extensive programming-specific functions such as bit shifting, masking, two's complement, IEEE-754 conversion, and more. You can enter data in decimal, hex, or binary, and types can be mixed freely. Coder Calc also features a full suite of scientific and engineering operations. The operations are tailored to your preferred orientation, so depending on how you old the device, you get a different experience.

There are extensive customization options for appearance and function. Graphically, it's made to look right at home on your iPhone. If you've always felt calculators needed shinier buttons, then Coder Calc is for you!

Excellent

Appreciate the updates when needed. Nice to have a simple calculator for iPhone that can do logic and hex operations!

Nifty little calculator - especially if you write code
'Groby' Blum

If you need a calculator that has support for decimal/binary/hex as well as lots of logic operations, this is one of the better ones. It also brings a full complement of arithmetic & trig functions, in case your programming takes you in the unknowns of actual math ;) For those of us always in love with the old HP calculators, it (of course!) supports RPN in additional to the more conventional calculator mode. And to make every programmers heart beat faster, you even get a multiline stack display ;)

Everyday programmer calculator

Far superior to the standard iPhone calculator, this fully featured calculator supports a wide range of functions perfectly tailored to the programming challenges I face on a day to day basis, including hex & binary support (with bit shifting and 2s complement), trig in degrees and radians and various other engineering functions. If you write code and could do with a decent calculator, this is the one for you!

Great Calculator, 1 Big Flaw For Me
SideshowRalphWiggum

I saw this calculator and read the reviews and saw that it was just what I was looking for: a good, RPN-capable, easy-to-use programmer's calculator to replace the built-in calc. So I bought it. Unfortunately, it turns out it's only capable of part of what I mentioned above: It is a simple-to-use, very good RPN-capable calculator, but it can't REPLACE the built-in for me. It loads WAY too slowly right now. When you need a calculator on your phone, you usually need it NOW. From the time you press the button, it takes anywhere from 5 to 9 seconds to come up! That's an eternity if you're standing in line somewhere to calculate a price, or gas mileage at the pump, etc. Hopefully, this is something the developer can and will fix. If so, I'll certainly revise my review to reflect the change. If not for this lag, I would gladly have given this app a full 5 stars. It's that good, once it starts up.

finally, an all-in-one solution!

Really well done! Hexadecimal +binary base conversion, love the flexibility in data entry - decimal/ hex/ binary, and the mix. Cool app!!

Good app, but...

Good app, it does exactly what it should do. Also, unlike the other "programmer" calculators, it looks good!. However, I wish the program would load faster. It does not inhibit the use of it, but it is just a little annoying. If this could be fixed, it would get the 5/5 from me.

Best value so far

Coder Calc so far has had the best value I've ever seen from the app store. I've tried at least 3 other RPN calculators, and they all work ok with varying degrees of comfort, coolness, and ease of use, but so far Coder Calc is the best by far. What I love about Coder Calc is the multi-line display, and especially the fact that even when something scrolls off the screen, it's still in the calculator's memory. Of all the other RPN iPhone calcs I've tried, only one other has multiple stack lines visible (Classic RPN Calculator), but if something scrolls off the screen above level 4, it's forgotten and gone forever. Coder Calc won't forget. Other than that, all other RPN calcs I've seen only show one or 2 levels, and to me it feels like tunnel vision. Coder Calc has an arbitrary-base logarithm key. I've never seen that on another calculator in my life, and I am truly impressed with this app. Usually I had to look up the change of base formula and figure out how to use it, but with the arbitrary base log key it's much more streamlined now. The developer has been extremely attentive and receptive to customer input, and takes our ideas and suggestions for further improvement seriously. I actually took a screen shot of Coder Calc and Photoshopped it to show the developer how to use space more efficiently to fit another row of buttons on it (dedicated SWAP key!!!), as well as ways to improve the user interface by dropping duplicate commands, making the stack lines numbered and scrollable, grouping closely related commands together (10^x, log, and EEX), and she wrote me back the very next day taking my ideas seriously, praising them, promising to look into them for the next version, and boosting my ego. :-) Odds are the next version will have more buttons and be more awesome. Long story short, customer service is excellent. Coder Calc also does logic-oriented operations in HEX and binary. All this for one dollar. I expect this to be the RPN calculator I keep after trying out all the other ones in the iTunes store.

Fantastic!

I bought this app after buying a much more expensive RPN calculator app. I love the fact that the stack is unlimited and that you can view multiple lines in the stack. Well worth the price.

Ok, needs work

To be a coder's calc, needs: 1s complement as well as 2s; ASCII/UTF codings, octal, consistency in operation and display. And Log base 2 of 1 is 0, not infinity...
