How to format an array

Li Chen

10/19/2006 7:49:00 PM

Hi all,

I have an array [1.0, 2.0, 3, 4,5,6]. I want to format all the elements
within the array into to this format "%5.3f", that is 5
spaces/characters for each number/element, followed by 3 floating
points. Any help will be appreciate.

Li

[1.0, 2.0, 3, 4,5,6].map { |num| "%5.3f" % num } #=> ["1.000", "2.000",
"3.000", "4.000", "5.000", "6.000"]

[1.0, 2.0, 3, 4,5,6].map { |n| sprintf "%5.3f", n }

Hot money chases higher interest rates, so no.

The ECB is fretting about deflation caused by the German surplus, and to
a lesser extent by the eurozone surplus.

the euro was already too high and yet it has been climbing

I can't say I'm very fussed. I've done my European travels for the year.
