Talk:Partial function

If a partial function associates with every element in its codomain precisely one element of its domain, then it is called a total function, or simply a function.
This doesn't sound right to me. I think the words codomain and domain should be swapped. The function described above sounds like a 1:1 function, not an arbitrary total function.

Partial Function from-set contains members not in the domain, i.e. domain is subset of the from-set. Total Function Domain is the entire from-set -Mikael-
