This application uses math.js for calculations. math.js has many functions. You can see list of functions from user-interface.
As you type mathematical expressions, the results are calculated automatically after you stopped typing. You don't need to press any button to calculate.
There are 4 different modes. All the modes have their own screen keyboard.
In programmer mode you can make calculations in 4 different bases and can see the results in 4 different bases.(hexadecimal, decimal, octal, binary) You can copy the results of calculations in 4 different bases.
In date & time mode you can make date-time calculations. For example, let's say you want to know how much time it is 13800 seconds minus 10000 milliseconds. You can use autocomplete for selecting time units like in the image below.
Here you can also make date-time calculations. Let's say today is 4 of April 2020. What is the date after 90 days. It is 3 of July 2020.
You can copy-paste input. You can copy the results of the calculations. You can ignore commas in calculations. You can set the number of digits in the result. You can set the precision in results.
Since Hasap is a progressive web app, you can download it and use it as an app. If you download it as an app, you can use it without the Internet.
I find the tools that I use frustrating and not functional enough. For example, Windows 10 has a great calculator. It has more functionality than this one. I definitely inspired by it.
- But you can not copy-paste whole strings to it.
- Let's say I did a long calculation like
2^4-145+4*23. Why I can't change 145 to 146? - I really like button pressed effect on-screen keyboard. But there is a small glitch which I found a bit annoying. When I press a button continuously It is not shown pressed continuously, there is a small glitch.
I used google as a calculator a lot. You can copy-paste text and change the string from the middle of it. But When I changed angle unit to degree why the results aren't changing.
I also used duckduckgo a lot. It wasn't good with trigonometric functions either.
Built with Angular CLI version 9.1.0.
Use npm i to install dependencies. ng s to run in development mode.
I also use angular-cli-ghpages for deploying my app to github-pages branch using the command ng deploy --base-href=/hasap/. Thanks for this useful library.
I hope this tool would be handy and useful for people.
