ENG button (like Casio calculators) on HP Prime



#2

Hello, i have always used Casio calculators now i bought the HP Prime & i have a simple question.

It is possible to change the number format (only the result) to engineering with one button?

I know it is possible to change the number format but it's tedious to change it entering to settings (i not always want the result in that way)


Thanks

You can write a short program to do this, using the reserved settings variable HFormat.

Hello Michael, thanks for the answer.

I have done this:

EXPORT eng(X)

BEGIN

LOCAL ans;

ans:=X;

HFormat:=3;

RETURN ans;

END;

it works fine but i have two problems:

1.I want to assign it to a button, like to be at CAS mode, the touch button "simplif" to have a button "eng"... is that possible?

2. I don't want that it changes the mode which i'm working.

In order to do that i've tried to put a HFormat:=0; after the RETURN but that didn't work.

Thanks :)

Maybe this could be added to the time/date/battery popup. Just noticed you can change the angle setting there (degrees or radians) via touching. I switch formats often going from scientific to financial and back again. Somewhat more tedious than it probably should be.
