Re: HP 39 GII Message #55 Posted by Gilles Carpentier on 14 July 2012, 4:18 p.m., in response to message #50 by Charles C(UK)
just few others speed tests for the 39GII :
FOR T FROM 1 TO 10000 DO END;
takes about no time... A loop from 1 to 100000 takes ~4 sec
The sum of n first numbers :
EXPORT Test(N)
BEGIN
R:=0;
FOR I FROM 1 TO N DO
R:=R+I;
END;
R
END;
Test(10000) gives 50005000 and takes ~1sec (31 with my 50G  with a loop, the 'sum' function use PSI function and is instantaneous)
About graphics :
FOR x FROM 0 TO 255 DO
FOR y FROM 0 TO 126 DO
PIXON_P(x,y);
END;
END;
takes only 3 sec wich means that the calc write 10000 pixels / sec
EXPORT Boite(N)
BEGIN
FOR I FROM 1 TO N DO
RECT_P( FLOOR(RANDOM(255));FLOOR(RANDOM(126));
FLOOR(RANDOM(255));FLOOR(RANDOM(126));
0;FLOOR(RANDOM(3)));
END;
FREEZE;
END
draws boxes on the screen with a black border and random color (grey level) inside.
Boite(100) takes about no time...
Boite(1000) takes less than 2 seconds.
Plot of fonctions is quite instataneous, zoom ...
These are good news... Bad news is that the current ROM version seems to have some bugs with power of complex numbers. I hope this will be corrected soon.
