Pow(sin($pi),2) + pow(cos($pi),2) – scientific floating-point calculations, pi-constant ((0xBEEF > 8) ^ 0xFFF0 – mixed binary, dec and hex numbers Some examples of acceptable expressions are: QCalc is also a powerful floating-point scientific calculator and supports all mathematical functions (sin(), cos(), tan(), exp(), ln(), …). Among others, the expressions can contain all bit-wise operators (>, |, &, ^, ~) as well as mixed decimal, hexadecimal and even binary constants. The most important feature of QCalc is that it accepts expressions in the C-syntax – with the same operands and precedence rules as in the C or C++ source code.

I begin with describing QCalc features and then I tell you how to download and launch it. But can your calculator accept complete expressions in the C-syntax, which you can cut-and-paste directly to and from your embedded code? How many buttons do you need to push to see your result in decimal, hex and binary? Well, QCalc can do this with less hassle than anything else I’ve seen out there. I’m sure that you already have your favorite calculator online or on your smartphone. Today, I’d like to start with my cross-platform Programmer’s Calculator called QCalc. In this blog, I’d like to share some of my tools with you. And these generally useful tools ended up in my Embedded Toolbox. Some of them proved to me more useful than others.

I use it all the time.Like any craftsman, I have accumulated quite a few tools during my embedded software development career.

The TI calculators automatically insert an “Ans” variable (a placeholder for the previous line’s answer) if you start a new line with an operator instead of an operand.įor me, it was worth buying both a Windows and Mac license.

It would be nice to have a “previous answer” symbol.

I appreciate Soulver having a second column that auto-updates as you type.

Having to type “=>” at the end of each line is typographically awkward.

Is it “as dec” or “in dec”? I frequently pick the wrong one.

I frequently get confused with base conversion syntax.

It would be great to say: 0x1234 > 5 & 0b111 For instance, bits 5.7 might be one field. I sometimes run into cases where a 32-bit integer is composed of several unaligned bit fields.

There are no bitwise shifts or inversions.

My needs are small, but with the pieces I do use, it performs extremely well. I don’t come close to using all the features in Calca: functions, unit/currency conversion, matrix math, derivatives, and so on. Everything from “=>” to the end of the line is rewritten to become a read-only answer. The trick is that it looks for “=” and interprets these as definition statements and it looks for “=>”, and treats these lines as problems to solve. SpeedCrunch is available for all platforms, but like many Open Source programs, the operation and user interface is clunky.Ī few months back, I found Calca, “the text editor that loves math,” for Windows and Mac. There is an iOS port, but I can’t stand the data entry. It’s great on the Mac, but there are not Windows or Linux ports.

I write code on Linux (work) and Mac (home), but my office Windows box ends up being my documentation reference, scratchpad, calculator, and everything else non-coding because I typically run my Linux IDE full-screen (bridged with Synergy, naturally). Ideally a Linux version would be available, too. It needs to minimally run on Windows and Mac.I don’t need or want Mathematica or Maxima. Or leave it running in the background without eating a ton of resources. This includes expressions ( 0x48+0x16) as well as base conversion ( 0xC3 as decimal or 0b110101 as decimal) and bitwise math ( 0xFC AND 0x7F). Be able to easily edit and copy previously-entered expressions.Be able to enter expressions similar to what I could do on a TI-85, back in the day, for example: 2^2+(2*10).I think I’ve finally found one worth mentioning.

For years, I’ve been searching for a good free-form symbolic calculator program that works across multiple desktop operating systems.
