What is rpCalc?

rpCalc

So, let’s talk about rpCalc. It’s a cool alternative to the usual Windows desktop calculator. This lightweight RPN calculator is perfect for everything from simple math to complex calculations!

What is RPN?

If you’ve used Hewlett-Packard calculators before, you’re familiar with reverse polish notation (RPN). With rpCalc, all four registers are shown right on the main screen, and you enter numbers first before doing any operations.

User-Friendly Design

One of the best parts? The look of rpCalc is consistent across all devices! It feels just like using a real calculator. You’ve got buttons for numbers and functions that you can click on with your mouse.

Easy Navigation

You can definitely click buttons or tap them, but here’s a neat trick: it’s even easier to use your keyboard! Just type in numbers and operators, or even commands (no need to worry about capitalization!). Plus, if you start typing a command and hit the “Tab” key, it’ll help finish it for you. For example, type “pi,” and bam! You’ll see the value pop up!

Unique Commands

Some commands might look a bit different than what you're used to. Like “RCIP” stands for 1/X, “tn X” means 10^X, “x<>y” is how you exchange values, and if you want to clear everything out, just hit “CLR.” Pretty handy!

Keep Track of Your Work

rpCalc keeps some recent calculations saved in its History View. You can easily switch this on by using the “OPT” menu. There’s also a Memory View that shows what’s stored in memory registers.

Customizable Settings

You can set rpCalc up to remember where it was last positioned on your screen. The “Settings” menu lets you change things like angle units and notation types. Want more decimal places or need to adjust how many history entries show? No problem!

A Great Alternative

This isn’t just another basic calculator; rpCalc serves as a virtual replacement for physical HP calculators too! It’s open-source software that handles various tasks like trig functions, logarithms, square roots, exponentiation—you name it!
