Infinity: Difference between revisions

=={{header|APL}}==

For built-in functions, reduction over an empty list returns the identity value for that function.

E.g., <code>+/⍬</code> gives <code>0</code>, and <code>×/⍬</code> gives 1.

The identity value for <code>⌊</code> (minimum) is the largest possible value. For APL implementations

that support infinity, this will be infinity. Otherwise, it will be some large, but finite value.

<lang apl>inf ← {⌊/⍬}</lang>
