Oracle: best way to deal with NULL values

I have this piece of code within a procedure:

 if val is NULL
    then 
    creb :=0;
   else 
     creb := val;
 end if;

Is there more elegant way to deal with null?

As a complement to Bohemian's answer, Oracle has the non-standard NVL -- and the NVL2 if you need an else case with a value different from the condition -- functions to deal with that issue.

creb := nvl(val, 0);

COALESCE has both advantages of being standard and accepting multiple arguments.

Use coalesce (), which returns the first non-null value in the list if values passed to it:

creb := coalesce(val, 0);
