IEEE-754 binary rep functions

How would one write elisp functions to convert
to and from the binary representation of a
IEEE-754 (single precision) floating point number?
I don't care about NaN etc.

#The perl would be something like:
$number = 1.0;
$binrep = unpack("H8",pack("F", $number))
# 3f800000 on a big-endian
$float = unpack("F",pack("H8", $binrep))
# back to 1.0
