array count values only works for integers and strings  If you happen to want counts for float numeric values  and you are heedless of small variations in precision or representation   this works    function arrayCountValues  arr       vals         foreach   arr as  val    array push  vals strval  val         cnts   array count values  vals     arsort  cnts     return  cnts      Note that I return  cnts with the keys as strings  It would be easy to reconvert them  but I m trying to determine the mode for the values  so I only need to re-convert the first  several  values   I tested a version which looped  creating an array of counts rather than using array count values  and this turned out to be more efficient  by maybe 8-10
