and my purpose is to convert -0.00 to 0.00 without affecting other negative values.How can I achieve this goal as I am not sure of how to approach? Thanks in advance for helping me out.
Unless this is rounding from something else SAS stores a value of -0.00 as 0. If this is external data when it is imported or read into a SAS data set it will be 0. The number of 0 decimals shown will depend on the display format used or defaulting, likely best4. or similar.
