Hi Juma,
We are planing to document this in detail soon, as we have made some changes here. Briefly however, if you want to restrict your data entry values to ONLY negative integers you should choose the "Negative integer". If your values can potentially include zero as well, you should as Hieu points out, choose the "Zero value storage" from the Data administration module, as well as set the "Store Zero Data Value" for this particular data element. "Negative integers" allow whole number values less than (but not including zero). "Positive integers" allow whole number values greater than (but not including zero). If you want to also store zeros for these number types, be sure to follow the procedure outline above. "Integer" allow whole number values, including zero. You will also need to enable the "Zero value storage" options in order to save a zero for this type as well. "Numbers" allow any real number. Note that we have disallowed invalid values such as "00" or ".123" or "12." or "1e34" (scientific notation). Also thousands separators are not allowed (e.g 1,000). Also, all values are restricted to less than 255 characters, due to restrictions of the data models (although I seriously doubt anybody is going to need an integer with 255 characters!). Like I said, we will document all of this soon, and it would be good to get peoples feedback on this, as we have tried to be more restrictive about the data types which DHIS2 accepts, in order to improve the quality of data entry, although it may not fit will all data entry workflows.
