Atom - Æṃ - Mode
Tags: arithmetic
Arity: monadic
This atom is monadic, which means it takes one argument.
Functionality
Return all elements that have maximal number of occurrences in z. Vectorizes at depth 1.
Details
Even if there are no ties, the output will be a list. 3,2,1,3 Æṃ will return [3] (though output formatting will hide that, unless you use ŒṘ).
