I'm pretty sure there's a better way to do it.

def number_in_fixed_width number, width
  string = number.to_s
  ' ' * (width - string.length) + string
end

number_in_fixed_width 42, 5    # => "   42"
number_in_fixed_width 123, 5   # => "  123"

Oh, thank you gnab! I was thinking about using `"%5s" % number` but `rjust` seems more powerful.

you can try this one out as well...

class Fixnum
  def fixed_width w
    to_s.rjust w
  end
end

1.fixed_with(5) # => "    1"

Here is another option:

class Fixnum
  def fixed_width width
    "%#{width}d" % self
  end
end

1.fixed_width(5) # => "    1"
