Tie::Comma, version 0.04

This module provides Yet Another way to format numbers with commas, this time via a tied hash. This makes it very easy to format a number while inserting it into a string.

EXAMPLES

# Simple formatting with commas:
$a = 1234567.89;
print "With commas: $comma{$a}"; => "With commas: 1,234,567.89"

# Specify number of decimal places:
print "1 decimal: $comma{$a,1}"; => "1 decimal: 1,234,567.9" print "3 decimals: $comma{$a,3}"; => "3 decimals: 1,234,567.890"

# Specify field width:
print "Min width: '$comma{$a,0,12}'" => "Min width: ' 1,234,568'

# In-string computations:
print "Seconds in a year: $comma{365 * 24 * 60 * 60}";

=> "Seconds in a year: 31,536,000";

DEVELOPMENT STATE

This is an early version of this module, so who knows what bugs lurk.

If you find any bugs, or if any behavior of Comma surprises you, I would be grateful if you could send me an email message about it. Thanks.
