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. Everything from “=>” to the end of the line is rewritten to become a read-only answer. I don’t come close to using all the features in Calca: functions, unit/currency conversion, matrix math, derivatives, and so on. My needs are small, but with the pieces I do use, it performs extremely well. There are no bitwise shifts or inversions.I sometimes run into cases where a 32-bit integer is composed of several unaligned bit fields. It would be great to say: 0x1234 > 5 & 0b111 For instance, bits 5.7 might be one field. I frequently get confused with base conversion syntax.Is it “as dec” or “in dec”? I frequently pick the wrong one. Having to type “=>” at the end of each line is typographically awkward.I appreciate Soulver having a second column that auto-updates as you type. It would be nice to have a “previous answer” symbol.

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.

I use it all the time.Like any craftsman, I have accumulated quite a few tools during my embedded software development career. #Speedcrunch programer calculator software# Some of them proved to me more useful than others. And these generally useful tools ended up in my Embedded Toolbox. In this blog, I’d like to share some of my tools with you. Today, I’d like to start with my cross-platform Programmer’s Calculator called QCalc. I’m sure that you already have your favorite calculator online or on your smartphone.

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 begin with describing QCalc features and then I tell you how to download and launch it.

#Speedcrunch programer calculator how to# 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. Among others, the expressions can contain all bit-wise operators (>, |, &, ^, ~) as well as mixed decimal, hexadecimal and even binary constants. 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(), …).
