Preserved numerical value when exporting to xls

EMC9 — Thu, 26 Oct 2017 07:23:47 GMT

Hi Experts

Need some help please , I am trying to export numerical data to excel /xslb.

I have tried to format the field with BEST/NUMX with no luck.

The numerical data is standard 16 digits e.g 1111222233334444.

when I export using the below export code :

proc export outfile="Location\&TEST_NO._&TRIM_FROM._to_&TRIM_TO._&NOW..xlsb"
dbms=excelcs data = SDR_TXSET replace;
sheet="DATA";

quit;

when I open the excel sheet the data displays like : 1,2226543+13 & when I expand and format the cell the data displays like

e.g 111122223334440 . which is incorrect.

Regards

Because of the 8-byte real format that SAS uses for storing numeric data, the precision is limited to ~15 decimal digits. What you see is normal behaviour for data in SAS datasets.

Thanks.

Since precision like that is not needed for statistics (the range of exponents in the real format is sufficient for either very large or very small values), this is usually no problem. Very often such large numbers are identification codes or such, and are therefore stored as character.
