Beginning in SAS 9.1, the DIVIDE function is available and returns
the result of a division even if one argument is zero. This scenario
will not produce the note about division by zero problems.

   data a;
     x=divide(12,0);
     put x=;
   run;

   x=I (this is uppercase i, not numeral 1)


The DIVIDE function divides two numbers and returns a result that is
compatible with ODS conventions. The function handles special missing
values for ODS output. The following list shows how certain special
missing values are interpreted in ODS:

.I as infinity

.M as minus infinity

._ as a blank


This function is documented beginning in SAS 9.2.
