🥇 Extremely Flexible & Very Advanced Scientific Calculator with User Arguments Definition, User Functions Definition, Functions Graphs, Scripts Programming and many other features.

Scalar is much more than a calculator. Scalar is a powerful math engine and math scripting language, that combines the simplicity of standard calculators with the flexibility of scripting. Thanks to Scalar, defining arguments and functions, as well as using them in subsequent calculations, expressions and functions graphs, has never been easier. You will see it shortly after getting familiar with available screens and options.

🎯 Main features:

🔹 Standard & Advanced Scientific Calculator
🔹 Extremely convenient calculator keyboard
🔹 Re-usage of previous calculations, just reference a constant that was created for your convenience
🔹 User defined arguments, as simple as x = 2
🔹 User defined functions, as simple as f(x) = x^2, f(x,y,…)=2*x+y
🔹 User defined random variables, as simple as rand X = rNor(0,1)+1
🔹 Beautiful function graphs, set variables, range, expression, interact with the chart!
🔹 Scripts writing, personalize and automate you work!
🔹 Rich set of examples built-in in the app!
🔹 Work saving and results sharing

👌 The definition of user elements has never been easier!

Using Scalar you can easily create user elements, below are examples of the natural mathematical syntax:

▶ scalar > x = 2
▶ scalar > y = 2 * x
▶ scalar > y
➥ e1 = 4.0

▶ scalar > x = 3
▶ scalar > y
➥ e2 = 6.0

👌 There is no need to save the results!

In Scalar, each result is assigned to an automatically created constant, see example:

▶ scalar > 2 + 3
➥ e1 = 5.0

▶ scalar > 4 + 6
➥ e2 = 10.0

▶ scalar > e1 + e2
✪ ➥ e3 = 15.0

👌 User functions give huge possibilities of personalization!

Defining user functions is just as simple as writing a formula

▶ scalar > f (x, y) = sqrt (x ^ 2 + y ^ 2)
▶ scalar > f (3,4)
➥ e1 = 5.0

👩‍🏫 Scalar was created by a mathematician, therefore it has built-in summation and product operators!

Scalar also supports summation and product operators, for example the number of prime numbers in the range of 2 to 1000

▶ scalar > sum ( i, 2, 10000, ispr (i) )
➥ e1 = 1229.0

⚡️ This is only a tiny part of available options!

It is only a presentation of a small part of the available mathematical functions. All implemented math elements exceeds several hundred.

👩🏻‍💻 At Scalar, you can write scripts!

🔹 The ability to write scripts is a unique feature among scientific calculators.
🔹 We all know how scripts significantly accelerate work.
🔹 Scalar provides a nice script editor with syntax highlighting & syntax hints.
🔹 Scripts can be saved and/or shared (pro version).
🔹 Start-up script is also supported (pro version).

📈 At Scalar you can create beautiful function graphs!

🔹 Visualization is important - no doubts!
🔹 Scalar provides the ability to create highly personalized function charts.
🔹 Functions graphs are fully interactive: values reading, scaling, zooming.
🔹 Function charts can be saved or shared (pro version).

I love this calculator and you can see my review history for what I have said previously... I had to drop a star because of this new rating request pop-up. I've given it multiple 5* reviews and it just keeps popping up asking for a review. Not just at boot up, but every time I go to it or adjust the size of the floater window I'm using it in. It is borderline unusable. Change your window to verify numbers, go back to Scalar and click 2 pop-ups. I have 4x pop-up interactions than calculations.

Thank you. The app cannot access your opinion on Google. All you have to do is give the appropriate answer in the popup by clicking the button, then the application will remember your choice and the popup will stop to appear. Thank you for your in depth review! :-) It is a pleasure, this motivates to develop Scalar Calculator further.

This is a good calculator and has an okay graphing environment, but where the calculator shines is the scripting environment, which has a nice programming language behind the scenes. If you need to script something quickly on your phone, this is your best bet. It's got a faster start up time than any other language you might use on your phone with a syntax that is simple enough to learn quickly. Sure, it's not Python or Lisp, but it works for most problems.

great math app, with one small bug on my device that hurts me inside like a not so gental cellmate. besides being a great calculator, it has a pretty nice scripting environment. It even allows you to run a script at startup, which lets you do anything from having some variables on hand to defining nearly any function that you can write. Unfortunately, I cant save the scripts on my device. I allowed it access to the file sustem but it still fails to write. Still my favorite calculator though.
