🥇 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).

🏆 Free version vs paid version:

You can take full advantage of the free version of Scalar, however some options will be unavailable. These are mainly the ability to save / open a script, save / open a chart, share calculations, share scripts and share charts. All these options can be found in the pro version.

So just got this to play around with while in samsung's dex mode... Hitting enter on the keyboard does not run the expression I entered, which really breaks this app to constantly switch from keyboard to tapping "go" on the screen (or using a mouse to click it). Haven't tried anything more than the most basic calculations yet but I imagine they'll work.

Hi. Thanks for using the SCALAR scientific calculator. Give SCALAR a chance. It is completely different from typical tools. Take a look at the video https://youtu.be/HUlEUaioogQ and tutorial https://scalarmath.org/wp-content/uploads/2021/11/Scalar-App-User-Manual.pdf . I will pay attention to Samsung Dex - I did not test it. Thanks! All the best.

OK, so I'm amending my first review because the developer of this application reached out to me. I explained the problem with the ads and they have agreed to adjust the intensity of the ads. It is very refreshing to hear this kind of response from a negative review. Because of this I am willing to give the app another chance and tentatively adjust my review. The app itself is nicely designed and intuitive. The functions I have used so far are really slick and useful for my purposes. Thanks, Scalar Math, for addressing my concerns! -----OLD REVIEW-----> So many ads. I uninstalled after the second time a 3 second video played with volume when I was trying to get the square root of a number.

Dear William, Thank you for your feedback. Scalar comes as a free application, fully packed with really advanced features. There is an option to upgrade or, for a fraction of price, to eliminate ads - this is really small fee. We, of course, understand inconvenience , that is way just ads elimination option was provided. Best regards, Scalar Math

This calculator is very powerful and intuitive to use, with advanced scripting functions for complex formulas, and I would've given this 5 stars except for a small flaw. I've noticed that the maximum values this can handle before returning infinity is rather small at only 2^1024, which is much too low for smaller numbers such as 2^512^512, which is quite simple for many other calculators to perform.

Dear Jaitin. Thank you for using Scalar and for your super review. Scalar is using double floating point representation, which - in my opinion - has a lot of advantages (for instance a broad spectrum of available mathematical functions). Obviously double representation has some limitations. Best regards.
