Is there a phrase or word to describe an algorithim or programme is complete in that given any value for its arguments there is a defined outcome? i.e. all the ramifications have been considered whatever the context?

A simple example would be the below function:

function returns string get_item_type(int type_no)
{
  if(type_no < 10)
    return "hockey stick"
  else if (type_no < 20)
    return "bulldozer"
  else
    return "unknown"
}

(excuse the dismal pseudo code)

No matter what number is supplied all possibiblites are catered for. My question is: is there a word to fill the blank here:

"get_item_type() is ______ complete"

?

(The answer is not Turing Complete - that is something quite different - but I annoyingly always think of something as "Turing Complete" when I am thinking of the above).
