the same is not exactly true for floats - although you can
use them as array keys you'll

their decimal part (essentially
a floor() seems to be performed on the float value. I have no
idea whether this is intentional,

Yes, and Yes!

ah yes, I should have looked it up, that said I find it rather odd that
is works let alone that it's intentional.
though thinking about it you could probably use it for some float val
distribution counting or something. I dunno, seems like it offers a handy
shortcut - although what that shortcut is escapes me just now :-)
A key may be either an integer or a string. If a key is the
standard representation of an integer, it will be interpreted
as such (i.e. "8" will be interpreted as 8, while "08" will
be interpreted as "08"). Floats in key are truncated to
integer.
