📗📙📘 Click and see the user guide in PDF 🥇 Extremely Flexible &Very Advanced Scientific Calculator with User Arguments Definition,User Functions Definition, Functions Graphs, Scripts Programmingand many other features. Scalar is much more than a calculator.Scalar is a powerful math engine and math scripting language, thatcombines the simplicity of standard calculators with theflexibility of scripting. Thanks to Scalar, defining arguments andfunctions, as well as using them in subsequent calculations,expressions and functions graphs, has never been easier. You willsee it shortly after getting familiar with available screens andoptions. 🎯 Main features: 🔹 Standard & Advanced ScientificCalculator 🔹 Extremely convenient calculator keyboard 🔹 Re-usage ofprevious calculations, just reference a constant that was createdfor 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 andautomate you work! 🔹 Rich set of examples built-in in the app! 🔹Work saving and results sharing 👌 The definition of user elementshas never been easier! Using Scalar you can easily create userelements, 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 noneed to save the results! In Scalar, each result is assigned to anautomatically 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 ofpersonalization! Defining user functions is just as simple aswriting a formula ▶ scalar > f (x, y) = sqrt (x ^ 2 + y ^ 2) ▶scalar > f (3,4) ➥ e1 = 5.0 👩‍🏫 Scalar was created by amathematician, therefore it has built-in summation and productoperators! 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 isonly a tiny part of available options! It is only a presentation ofa small part of the available mathematical functions. Allimplemented math elements exceeds several hundred. 👩🏻‍💻 At Scalar,you can write scripts! 🔹 The ability to write scripts is a uniquefeature among scientific calculators. 🔹 We all know how scriptssignificantly accelerate work. 🔹 Scalar provides a nice scripteditor with syntax highlighting & syntax hints. 🔹 Scripts canbe saved and/or shared (pro version). 🔹 Start-up script is alsosupported (pro version). 📈 At Scalar you can create beautifulfunction graphs! 🔹 Visualization is important - no doubts! 🔹 Scalarprovides 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). 📳ScalarMath.org More details on: ScalarMath.org 👌 Enjoy using ScalarScientific Calculator!
