sprintf Question

[BStopp]

According to my books.. if you put a number in your format it makes the result that many characters as a minimum. When dealing with floating point numbers, does the decimal count as one of those characters?

Example:
$number = sprintf("%05.1f", 0)

This results in 000.0
Technically it's 5 characters, but when dealing with numbers, i've never heard of the decimal counting in the minimum field width.

In order to get this: 0000.0
my code would have to be

$number = sprintf("%06.1f", 0)

Correct?

Certainly seems to be the case...

#!/usr/bin/perl

@numbers = qw(176.4 22.1 998.54 33.34 21 17.4 1.6);

foreach $number (@numbers) {
  $formatted = sprintf("%06.1f", $number);
  print "$number -> $formatted\n";
}

gives output:-

[blue]176.4 -> 0176.4
22.1 -> 0022.1
998.54 -> 0998.5
33.34 -> 0033.3
21 -> 0021.0
17.4 -> 0017.4
1.6 -> 0001.6[/blue]

Kind Regards

just to check this was not a perl peculiarity, i tried gcc on a few samples. Same as duncdude
