Different between 6. And best6.

[PeterClemmensen]

Probably better exemplified with a non-integer value

data _null_;
    a=123.456;
    put a= 6. /// a= best6.;
run;

With the Best6. Format, SAS chooses the 'best' notation inside an output field with a width of 6 to hold both numbers and delimiters.
