https://communities.sas.com/t5/SAS-Programming/on-format-informat/m-p/49887#M10397 i have a value of 171,775,417,252.01600 with a format of 25.5. How come when I change the format to 25.3 the decimal value becomes .017? And then when I changed the format to 25.5 again it again got the .01600 value. How does SAS round decimal numbers?<BR /> <BR /> Thanks!<BR /> Milton Mon, 01 Feb 2010 11:26:26 GMT milts 2010-02-01T11:26:26Z https://communities.sas.com/t5/SAS-Programming/on-format-informat/m-p/49887#M10397 i have a value of 171,775,417,252.01600 with a format of 25.5.
