called on reduced expression

This fixes the following bug: input i+10*sqrt(i)

Scenario: write the script:

def squares():
  for i in range(660):
    forward(L)lo)

Put the cursor right of "lo" and press backspace.

as it might be destroyed

This fixes the following crash: input 1, OK, input ans/[], go up to the history --> crash

This fixes the following bug: input _ns, go to additional results -->
crash

…function

Added a condition for being considered empty.
Allows axis("on") or axis((0,1,2,3)) to display something with show()
This behavior is the same as the python module

Scenario: write a ascrip "from matplotlib.pyplot0 import *" than open
the variable box

Scenario: add the script

then autocomplete after the last c.

expression contains a unit but we can't extract it (2^_min for instance)

No scenario, but it seems right to reset m_shortenResultCharCount

…esInScript

Example script:
from turtle import *
hideturtle()

We had "hideturtle" in the local variables, and "hideturtle()" in the
imported. Now we should only have the latter.

To prevent crashes caused by failed casts from char to float, removed optimization.

denominator() at reduction - there is no reason that there is no unit at

containing matrix of complex form (for instance ConfidenceInterval).

This fixes the following bug: input (2_m*confidence(0.2,12))^(-1) -->

…ecking

for node unicity and the insertion index computation

Did not fit or missed a space

It added color(|)/color(,,) instead of just color(|)

Scenario (crashed only on the calculator):

script1.py
from script2 import *
a=1

script2.py
from script1 import *
b=2

instead of at reducing (revert previous commit)

This fixes the following bug: input log(0*f(_t)) --> crash due to an
infinite loop where we remove/add 1 before the multiplication

Scenario:
1 EXE MATRIX MATRIX Down Down 1 Up Up -> it crashed

It is now possible to specify the color of the plot through a third positional argument in the plot function. However, is a keyword (color or c) is then used, it will override the previous color command.

Fix the broken simplification test 1/identity(2)^500

The result should be 0*[[1,0][0,1]]^500, or, maybe later, [[0,0][0,0]]

instead of float computation to avoid precision errors, by default the
arrow size is decided in pixels.

should not be equal to 0 but to Matrix(0)

Compute everything in pixels + fix glitch when zooming on the tip of
arrow(0,0,2,3)

the object are ordered in a table. Otherwise, the compiler is free to
order them as it wants.

This fixes the test on the device: 10_m^2→_mm×_km simplifies to 10×_km×_mm

implementation of libm (hypotf is not as accurate on the device)

This saves space + avoids clashes with the NumWorks Workshop when
exchanging scripts

If the symbol replacement led to an undefined reduce equation, we did
not realize we could try without replacing the symbol.

Scenario: Execute the script parabola.py, open the variable box, select
any leaf, enter, open the variable box again -> no variables are loaded
anymore

We now erase the turtle before writing text. This way we can redraw it
on top of it, preventing overlapping and remanent images.

Those scripts are causing issues :
goto(-30,50)
write('coucou')
left(270)
goto(30,50)
write('oui')
-----------
up()
goto(-30,50)
write('coucou')
goto(30,50)
write('oui')

Scenario: write a script, execute it in the console and open the
variable box, go back to edition and trigger autocompletion.
