## Re: Value of a E number

Although @Reeza's post is rather terse, he is probably spot-on to the problem. Numbers in that range are often encountered when the internal representation of numbers in SAS (8-byte real) causes problems stemming from the decimal-to-binary conversion (ie 0.1 cannot be correctly stored as a binary number).

In such cases, apply the round() function to get rid of inaccuracies happening far to the right of the decimal point.
