Warning: A non-numeric value encountered in /web5/aldweb/www/aldweb_com/www/thread.php on line 257

Sujet n° 1001	Negative number display problem
le 03/12/2004 @ 21:13 par Chuck	Negative numbers between 0.0 and -1.0 do not display with a minus sign. All negative numbers greater than or equal to -1.0 display properly. The following code will show the problem: P=0.45 N=-0.67 N$="P= " + STR$(P,2) N$=N$+" N= "+STR$(N,2) I=MESSAGEBOX(N$,1) Both P and N will show as positive numbers on screen. All calculations seem to operate properly. It is just a display issue. UPDATEFIELD has the same display problem. Any ideas?

I suspect that the STR$ function is the source of the issue.

Indeed, I think that I only tested it with positive numbers! You are going to be nominated Top iziBasic Bug Finder, together with our friend gmigueis! But, for the NUMFIELD, it is normal that it accepts only positive values, this is a Palm OS restriction, not an iziBasic one... @+ aldweb

It may indeed have the same limitation as entering negative numbers from the graffiti pad. In my application, the negative numbers are a baseline credit that is not allowed to be changed. I display them, but ignore changes, so I don't know what would happen if I read them back from a NUMFIELD.

[-1.0] works fine with me. So, I believe that the problem only occurs with [-0.xx] values! And also when doing STR$(A,n) with n>=0 (if n<0, display is correct). Now, I have to dig into the source code of iziBasic... As for the NUMFIELD issue, here is a copy & paste of Palm OS API doc: If checked, only the characters 0 through 9 and associated separators are allowed to be entered in the field. The associated separators are the thousands separator and the decimal character. The values of these two characters depend on the settings in the Formats prefs panel. So, it seems that the minus sign really is not taken into account when the user keys in one number, as I thought until now. And your own test have proven that someone could force displaying a minus sign in a field anyway! But it has to be by programming... Cheers, @+ aldweb
