[phpesp-dev] length and precision fields in the Questions tab

[Angelopoulos, K. <Kon...@ap...>]

Hi Guys,

Im wanting to update the faqs and introduce a tutorial for phpESP
but need some clarification on the numeric question type and the
use of the precision and length fields.

As I see it, and please let me know if this is incorrect, when the
length is specified for a numeric question type both the size of
the text box and the maxlength are affected. This is also true when
only the precision field is specified/set.

Example. I want the user to submit a number that has no more than 5 digits
so I set the precision
to 5 hoping that the maxlength is set at 5 but what really happens is that
the 5 (precision) is added to the default length (which is 10) and 1 is
added
to allow for the number to be signed so in actual fact the maxlength ends up
being
16. Furthermore the length field is also changed to 16.

I can understand adding 1 to allow for sign but what's the purpose of adding
the length
to the precision? Is precision meant to be used to indicate the number of
decimal places?

Also am I right in saying that the only other question types where length
and precision
have any affect are for the rate(scale 1..5)type, the text box type and the
essay box type
with the date type having a noneditable default length of 10 and precision
of 10?
