Scalar Lite is an exceptionally flexible and advanced scientific calculator, far surpassing the capabilities of a standard calculator. It's a powerful math engine and scripting language, designed for both simpliCity and advanced functionality. Define user arguments, create custom functions, generate function graphs, and write scripts – all within a user-friendly interface. Scalar Lite empowers you with the tools to tackle complex calculations with ease and precision.

Key Features:

* **Comprehensive Scientific Calculator:** Offers a full suite of scientific functions.
* **Intuitive keyboard:** Designed for efficient and convenient input.
* **Calculation History & Re-usability:** Easily reference and reuse previous calculations using automatically created constants.
* **User-Defined Arguments & Functions:** Define variables and functions as simply as writing equations, e.g., `x = 2`, `f(x) = x^2`.
* **Random Variables:** Incorporate randomness with user-defined random variables like `rand X = rNor(0,1)+1`.
* **Interactive Function Graphs:** Visualize functions with customizable graphs, including variable settings, range adjustments, and interactive exploration.
* **Scripting Capabilities:** Personalize and automate your workflow with a built-in script editor featuring syntax highlighting and hints. Save and share your scripts (pro version).
* **Rich Examples:** Get started quickly with a collection of built-in examples demonstrating various features.
* **Save & Share:** Save your work and share results (pro version).

**Effortless User Element Definition:**

Scalar Lite's syntax mirrors natural mathematical notation, making it incredibly easy to define user elements. For example:

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

Subsequent changes to variables are instantly reflected in calculations, without the need to save results.

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

Each result is automatically assigned to a constant (e1, e2, etc.) for easy reference:

```
▶ scalar > 2 + 3
➥ e1 = 5.0
▶ scalar > 4 + 6
➥ e2 = 10.0
▶ scalar > e1 + e2
✪ ➥ e3 = 15.0
```

**Personalized Function Definitions:**

Create custom functions with ease, just like writing a formula:

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

**Advanced Mathematical Operators:**

Scalar Lite includes built-in summation and product operators, demonstrating its power:

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

**Scripting for Efficiency:**

Scalar Lite's scripting feature, a rarity among scientific calculators, significantly streamlines complex tasks. The app provides a dedicated script editor with syntax highlighting and hints, allowing you to save, share (pro version), and even run startup scripts (pro version).

**Visualize with Interactive Function Graphs:**

Create and interact with highly customizable function graphs. Explore values, zoom, scale, and save or share (pro version) your charts.

**Free vs. Pro Version:**

The free version of Scalar Lite offers a comprehensive set of features. The pro version unlocks advanced options like saving/opening scripts, saving/opening charts, and sharing calculations, scripts, and charts.
