You may consider to slightly rewrite the requirements:

If it's a number, strip superfluous details; otherwise leave it as it is.

This specification leads to the following implementation:

$elt = is_numeric($elt) ? floatval($elt) : $elt;

To return the modified array array_map() seems to be appropriate.

Please wrap your lines to a reasonable width (see e.g.
<http://www.softdevlabs.com/personal/Usenet101.html#LineWrap>). TIA.
