perl - get number of elements in an array


is there any way to get the number of elements an array has?
say i have @array = ("one","two","three","four","five","six")
is there a possible way to get the number of how many elements there are from
$array[0..$#array] and then assign it to a variable?

in longhand you would explicitly request a scalar interpretation of it, e.g "$num = scalar @array". it's not needed, but does make it slightly clearer for when you can't be bothered to comment your own code.
