I don’t think we should allow decimal numbers in the first place, eg it cant be 0.5 people with malaria or vaccines given. But Jason pointed out that regex might be the better solution for this in any case. Feel free to improve, I don’t have strong opinions on this.

Hi all, my way is easy and simple. Cast to Double and compare with new
Double(0). new Double(value).equal(new Double(0)) ? how do you think?

[jason (Jason Pickering)]

Hi Bob,

I might suggest just a small change.

^[0]*[\.,]?[0]*$

Escape the period and add a comma for some locales that use commas
instead of periods. I am not aware of other decimal points, perhaps a
semicolon?

I am a bit confused though about the concept here. Values in DHIS are
stored in the DB as text, as far as I can tell. People should be
allowed to enter decimal values I think. We have an data element
(Number of liters of fuel). There is no reason why this could not be
entered (and as far as I know, it is) in decimal values. I am sure
there are other examples. Perhaps the validation rules is a better
place to put these types of rules? It sure would be nice to have Regex
capability there, to allow people that are so inclined to create
expressions for validation that would just be evaluated with a regular
expression.

Regards,
JPP

[bobj (Bob Jolliffe)]

I don’t think a java.util.regex solution would be hugely more complicated. One advantage is that all it expects is the string datavalue. If casting to a double you might also need to catch a class caste exception to be on the safe side. ie you have to ask is it a double first before you can ask is that double = zero.

Cheers
Bob

I suppose dataelement could have an extra string properties for an (optional) regex. This could be populated with generic defaults for different value types though that is maybe too wasteful. Anyway a user could then create more specialised regexes for particular dataelements. Mind you not too many people are “so inclined”.

This script will not working fine. new Double(“0.001”).intValue()==0 is

true but it must be false.

I thing it must be new Double(value)==(new Double(0))

what do you thing ?

I don’t think we should allow decimal numbers in the first place, eg it

cant be 0.5 people with malaria or vaccines given. But Jason pointed out

that regex might be the better solution for this in any case.

Maybe something like

^[2][.]?[0]$

Start word. Read any number of zeroes followed optionally by a ‘.’ followed

by any number of zeroes. End word.

From my emacs buffer, M indicates a match

0 M

003

0.00 M

0.03

.000 M

00.0 M

008000

Feel free to improve, I don’t have strong opinions on this.

True, not that many people are inclined but there are some of us that
find them quite useful. i suspect that many of the most common could
easily be populated as defaults, and developed by those that actually
need it.

I would see this as a huge advantage if implemented.
Let me list some of the things I am thinking about.
1) Min/Max--accept only values 1-199 (^([1-9]|[1-9][0-9]|[1-9][0-9][0-9])$)
2) Identification numbers--for instance, a US Social Security Number
(\b[0-9]{3}-[0-9]{2}-[0-9]{4}\b). Could be handy for the Patient
module especially.
3) Lat/long. I do not know exactly what this would be, but something
like accept number between -180 to 180. Handy for GIS.
4) A decimal value. Perhaps one should be forced to enter a decimal
value, like a persons temperature. [-+]?\b[0-9]*[\.,][0-9]+\b

I agree with Bob. It seems that we must assume that the value is going
to be something that is actually a double just because it is supposed
to be a number. It seems hard to imagine that a number greater than
the range available for a double would even be entered in DHIS, but
who knows...it could happen.

Blueprint anyway? Lars, you don't seem so keen on this, but maybe this
is just for this particular use case, i.e. determining if the value is
zero or not.

Regards,
Jason

Hi Bob,

I might suggest just a small change.

^[0]*[\.,]?[0]*$

Escape the period and add a comma for some locales that use commas
instead of periods. I am not aware of other decimal points, perhaps a
semicolon?

True. This is better.

I am a bit confused though about the concept here. Values in DHIS are
stored in the DB as text, as far as I can tell. People should be
allowed to enter decimal values I think. We have an data element
(Number of liters of fuel). There is no reason why this could not be
entered (and as far as I know, it is) in decimal values. I am sure
there are other examples. Perhaps the validation rules is a better
place to put these types of rules? It sure would be nice to have Regex
capability there, to allow people that are so inclined to create
expressions for validation that would just be evaluated with a regular
expression.

I suppose dataelement could have an extra string properties for an
(optional) regex. This could be populated with generic defaults for
different value types though that is maybe too wasteful. Anyway a user
could then create more specialised regexes for particular dataelements.
Mind you not too many people are "so inclined".

Cheers
Bob
