How do you strip the unit from any number in SASS?

Question

I know you can strip units from numbers in SASS when you know the unit before-hand like this:

$number: 16px;
$without-unit: 16px / 1px;
@warn $without-unit;

I think you'd have to add a custom Ruby function to strip the units (see the documentation on adding custom functions). It would look something like this, I think (warning, untested):

module Sass::Script::Functions
  def strip_units(num)
    assert_type num, :Number
    Sass::Script::Number.new(num.value)
  end
end
