Autocompletion in the Python editor

The Python script editor application now has an autocompletion feature. When users begin typing, the app will make a suggestion in gray.

  • To accept the suggestion, press the ** Right arrow ** or ** OK ** key.
  • To refuse the suggestion, press ** Back ** or just continue typing.
  • To get a new suggestion, press the ** Up arrow ** or ** Down arrow ** key.
  • All possible suggestions from the prefix entered are listed in the menu of the ** var ** key.

In the execution console, the menu of the ** var ** key displays the list of functions and global variables contained in the imported scripts.

Improvement of Python’s turtle and matplotlib modules

matplotlib.pyplot
  • The plot, scatter, bar, hist and arrow functions of the matplotlib.pyplot module now take an additional argument which allows users to specify the color. For example, to display a cloud of red dots: scatter([0,1,2],[2,4,7],color ="red“).
  • For the plot function it is possible to write the name of the color as a third argument: plot([0,1],[2,5],"red")
  • The keywords accepted for colors are listed in the menu of the Toolbox button: Modules> matplotlib.pyplot
  • It is also possible to adjust the size of the arrow function by writing: ` arrow(0,0,1,1,head_width=0.1) `
turtle
  • The new write("text") function of the turtle module allows users to write the text placed as an argument at the position where the turtle is located.
  • The argument of the circle(r) function of turtle can now be negative: the circle is then drawn in the opposite direction.
  • In the turtle module, it is now possible to use the colormode() function. colormode(1.0) changes the color mode to 1.0 and the colors must then be defined by tuples of type (0.5,1.0,0.5) while colormode(255) changes the color mode to 255 and the colors are then defined by tuples of type (128,255,128). By default the color mode is 255.

Additional results in the Calculation application

It is possible to go up in the history to show additional information on the result of particular calculations, thanks to the menu made up of three dots.

  • When the result is an integer, the calculator gives the following additional results: hexadecimal form, binary form and integer factorization where relevant.
  • When the result is a fraction, the calculator gives the following additional results: mixed fraction and Euclidean division of the numerator by the denominator.
  • When the result or the input is sin(x) or cos(x), the calculator gives the following additional results: angle, value of the cosine and sine and a representation of the trigonometric circle.
  • When the result is a complex number, the calculator gives the following additional results: absolute value, argument, real part, imaginary part and a representation in the complex plane.

Units

The Calculation app is now ready to handle calculations with units.

  • Units are prefixed by the character _ and and named by their International System of Units symbol, e.g. _m for meters.
  • A new section in the toolbox menu lists all the units that can be used.
  • The result of a calculation with units is displayed with the most relevant unit. For example, the calculation 30_s+30_s gives the result: 1_min.
  • It is also possible to perform conversions by using the arrow key sto→. For example, to convert 3 meters to centimeters, type: 3_m→_cm.

Enhancement of the Python application

Version 12.2.0

November 12, 2019

Parametric and polar functions

It is now possible to plot polar and parametric functions in the Functions application. The application has three modes: cartesian, polar and parametric. To choose the mode you want, select the name of the function and press OK.

  • To change the curve type (cartesian, polar, parametric), select the name of the function and press OK, then go in the Curve Type section.
  • It is possible to change the definition domain of a function by selecting the name of the function and pressing OK, then go in the Domain of definition section.
  • By default, the definition domain of polar and parametric functions is 0..2π.
  • By default, the definition domain of cartesian functions is -inf..inf. You can reset it by typing inf ou -inf.
  • By adjusting the definition domains it is therefore possible to plot piecewise functions.
  • The expression of a polar function needs to use the θ symbol, it can be typed using the x,n,t key.
  • The expression of a parametric function needs to be typed as a column vector of size 2. The first coefficient is the expression of x(t) while the second is the expression of y(t).

  • When the input or the result is too long and exceeds the screen, lateral arrows are displayed to indicate that you can scroll the line.

Improved graph navigation

  • It is now possible to type directly on the keyboard the value of the cursor abscissa.
  • In the Functions app, when displaying a tangent, it is also possible to type directly the abscissa at which to place the tangent.
  • In the Functions app, the Calculate menu available via the OK key now allows you to search for inverse images. Be aware that the antecedent must be located in the window to be found.

Addition of special characters

The texts in the menus and the interface now show the accented characters in some languages.

Enhancement of the Python kandinsky module

  • The color function now returns a tuple of the type (r,g,b).
  • The kandinsky functions requiring a color as an argument accept a color defined by a tuple (r,g,b).
  • New function that fills a rectangle of origin (x,y) : fill_rect(x,y,width,height,color).
  • The draw_string function accepts two new optional arguments, the color of the text (color1) and the background color (color2): draw_string('text',x,y[,color1][,color2]).

Other improvements

  • The maximum size of the matrices has been increased to 10*10.
  • Better handling of the battery icon: the calculator warns the user early enough in case of a low battery to prevent it from switching to DFU mode when charging.
  • random is no longer processed accurately so that it is not simplified.
  • When calculating an integral, if the user has previously stored a value in the variable used as an integration variable, this value is not substituted in the calculation.
  • The symbolic calculation has been removed from the software in order to comply with some exam regulations.
Special thanks

We would like to thank Xavier Andréani who helped us release this update.


Version 10.1.0

March 13, 2019

Exact calculation with complex numbers

The results of calculations involving complex numbers are now given in exact and approximate format.

  • Complex number quotients are simplified.
  • Complex number arguments are given using pi.
  • In the Settings application it is possible to choose the number format in the Complex format section. For example, the option Real, set by default, gives only the real roots of the polynomials. With this option, sqrt(-1) returns the result: unreal. You can also enable the Cartesian and Polar options that give complex results in cartesian or polar form. In this case, the polynomial roots are complex and sqrt(-1) returns i or exp(i*pi/2) depending on the setting.

Turtle module in Python

It is now possible to use the turtle module in Python. It is a simple and ideal drawing tool for teaching algorithmics.

  • The functions available in the turtle module are specified in the Modules section of the Toolbox menu and in the Catalogue.
  • The drawing can be interrupted by pressing the Back button.
  • The Python app has a new example script (squares.py). To draw the figure, run the command squares().

Improved graph interface

  • The colors of the grid now indicate the main and secondary graduations.
  • When the frame does not show the axes, you can still see the graduations.
  • If graduations values overlap each other, only the extreme values are displayed.
  • The automatic zoom of some functions such as sin^2+cos^2 has been adapted.
  • The legend of the graph takes into account the domain of the function. f(x)=x/x returns the value undef in 0.
  • When the user disables the Y auto option and adds a function, the zoom remains the same.

Other improvements

  • In Natural writing mode, when dividing a multiplication, the fraction line is drawn over the entire multiplication.
  • In the Calculations app, when the result is a polynomial (e. g. x^2+2x+1), the powers are sorted in descending order.
  • In the Calculation and Sequences apps, the symbol “=” has been added next to “f(x)”/ “Un”.
  • The maximum limit of the mu/sigma ratio has been increased in the Probability application.
  • Correction of rounding errors.
