[HP Prime] plotfunc() bug in CAS - Chris Pem10 - 12-03-2013

In CAS view enter the following:


plotfunc(SIN(x))


The result is a tiny plot. Now selecting the tiny plot and copying it to the stack results in the following:


plotparm(x+(i)*sin(x),x=5...5.0125)


Notice the extra dot in the x range. It is necessary to remove the extra dot for the plotparm() function to work.


I uploaded a screencast of the bug here:

[EDIT]


Perhaps the 3 dots are fine (the first is a decimal) and only a space is needed:


plotparm(x+(i)*sin(x),x=5. ..5.0125)


[EDIT 2]


Another bug in plotfunc() and/or plotparm():

Indeed a bug in plot for exp(), confusion with plotting an exponential law, I have fixed it in giac source, will certainly be available with the next HP firmware update. Until then, enter the variable and it will work (plotfunc(exp(-x^2),x))
