The "format" command

[Didier Lachieze]

format is a CAS command while a PPL program is essentially executed in Home mode, so you have some adjustments to do.
You can refer to this excellent tutorial: HP Prime CAS programming

In your case the trick is to build a string with the parameters you want to pass to format:

Code:

EXPORT FormatTest()
BEGIN
LOCAL s;
s:="9.3456," + STRING("s3");
s:=CAS.format( s );
MSGBOX( s );
END;

Or you can use STRING instead of format:

Code:

EXPORT StringTest()
BEGIN
LOCAL s;
s:=STRING(9.3456,5,2);
MSGBOX( s );
END;
