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
cursor (issue numworks#1458 on GitHub)
This fixes the following bug: input _ns, go to additional results --> crash
arguments in float instead of coordinates
matplotlib shape)
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 from matplotlib.pyplot import *\nfrom math import *\n\ng=9.81\n\ndef x(t,v_0,alpha):\n return v_0*cos(alpha)*t\ndef y(t,v_0,alpha,h_0):\n return -0.5*g*t**2+v_0*sin(alpha)*t+h_0\n\ndef vx(v_0,alpha):\n return v_0*cos(alpha)\ndef vy(t,v_0,alpha):\n return -g*t+v_0*sin(alpha)\n\ndef t_max(v_0,alpha,h_0):\n return (v_0*sin(alpha)+sqrt((v_0**2)*(sin(alpha)**2)+2*g*h_0))/g\n\ndef simulation(v_0=15,alpha=pi/4,h_0=2):\n tMax=t_max(v_0,alpha,h_0)\n accuracy=1/10**(floor(log10(tMax))-1)\n T_MAX=floor(tMax*accuracy)+1\n X=[x(t/accuracy,v_0,alpha) for t in range(T_MAX)]\n Y=[y(t/accuracy,v_0,alpha,h_0) for t in range(T_MAX)]\n VX=[vx(v_0,alpha) for t in range(T_MAX)]\n VY=[vy(t/accuracy,v_0,alpha) for t in range(T_MAX)]\n for i in range(T_MAX):\n arrow(X[i],Y[i],VX[i]/accuracy,VY[i]/accuracy)\n grid()\n show()tan(if :\n \n celse:\n )c then autocomplete after the last c.
depends on the System settings
Ion::Haptics::isEnabled is per platform.
This fixes the following bug: add the sequence, u(n)=2^n. On the graph, go to "sum of terms" and try to sum terms from 0 to 18 by moving the cursor. It hangs.

Add the possibility to use a double-typed evaluator when tracing a curve, useful when errors caused by float approximation mess with the drawing. Change-Id: I3ab410deec4823149239b0a26b1885fd2a493226
