How do I format a number in SAS?
Reading SAS Numeric Format There are two components in a SAS numeric format. The number of columns (width) v of the output and the number of decimal places. The SAS system uses floating-point representation referred to us as W.D, where W is the width and D is the number of digits to the right of the decimal place.
