Numeric Variable integer or float

SASSLICK001 — Fri, 03 Feb 2017 17:40:04 GMT

Hi All

How can I find a sas numeric variable whether its an integer or float? If its a floating numeric variable i need to know significant digits existing in the data?

Can someone throw some ideas?

SAS numeric varables are always real number.

If you want to know if the value contained is a whole number, check if int(var) = var.

Handle integer case ;

Else do ;
Handle non- integer case ;
End ;

Note that you may have issues if try to search for values with certain decimal values as storage precision may not exactly match your expectation and may have to do something like:
