Quick question

Something like:

[-1, -5.5, -44, -3.4432, 33.33].each { |x| puts sprintf("%12.5f", x) }
   -1.00000
   -5.50000
  -44.00000
   -3.44320
   33.33000

or maybe

[-1, -5.5, -44, -3.4432, 33.33].each { |x| puts sprintf("%1s%12.5f", x

< 0 ? '-' : ' ', x.abs) }

- 1.00000
- 5.50000
- 44.00000
- 3.44320
    33.33000

or maybe:

[-1, -5.5, -44, -3.4432, 33.33].each { |x| puts sprintf("%+5.5f",

x).sub('+',' ') }

···

-1.00000
-5.50000
-44.00000
-3.44320
33.33000

Alright, I feel like an absolute idiot, but the question is simple, and
30 minutes of looking hasn't yet yeilded the answer.

I want to take a float (say 0.0) and output it with a space in front if
it's positive, - in front if it's negative, and be able to specify how
many numbers after the decimal get printed (padding with zeros). This
will be used to output currency, and I just know there's a simple way to
do it with Ruby, but not finding it. :slight_smile:

Sorry to bother you all.
