• Fix bug in format_price that caused an extra space to be inserted in some situations, and no space in others, between the currency string and the number.
• Add support for gigabytes (formerly only kilo and mega) to format_bytes. (Thanks to Oeyvind Flaam <flaam@flaam.priv.no>)

Changes for version 1.42 (May 17, 2000)

• Fixed bug in format_picture that was causing subsequent calls to return the previous result and the current one concatenated together. This is actually due to a bug in Perl, but a workaround was implemented. To avoid this problem in your own code, don't use code like this: "my VARIABLE = EXPRESSION if CONDITION" because if the CONDITION is false, the previous value of VARIABLE will still be there, even if it had gone out of scope! This bug was pointed out by Buddy Burden <buddy@barefoot.net> on 21 Mar 1999, Frank Tobin <ftobin@uiuc.edu> on 11 Jun 1999, Mark William Rostron <mrostron@us.oracle.com> on 12 Dec 1999, and Ben Tilly <ben_tilly@hotmail.com> on 16 May 2000. Fix suggested by Buddy Burden, Mark William Rostron, and Ben Tilly.
• Fixed bug in round() that was causing e.g. round(1.005, 2) to return 1 instead of 1.01. This is due to the vagaries of floating point arithmetic. I changed .5 to .5000001 in the rounding formula and added a check for this in the test suite. That seems to fix it but please let me know if you experience any weird results. This bug was reported by Kentaro Takatomi <kentaro.takatomi@msdw.com> on 25 May 1999.
• Fixed several points in the code where 'use of uninitialized value' warnings were generated. Reported by Frank Tobin <ftobin@uiuc.edu> on 11 Jun 1999.
• In format_picture, replaced the use of $_ with a locally scoped variable ($char). This should reduce interference between this routine and any use of $_ by the calling program. Bug report and suggested fix by Mark William Rostron <mrostron@us.oracle.com> on 29 Dec 1999.

Changes for version 1.41 (Nov 30, 1998)

• Fix 'undefined value' warnings in format_picture
• Fix bug in format_picture to show decimal point if and only if it is present in the picture string (bug reported by Michael Scoltock <scoltock@ictp.trieste.it>)
• Fix bug in format_price that would suppress currency symbol if no decimal digits (bug reported by Michael Scoltock <scoltock@ictp.trieste.it>)

Changes for version 1.40 (Nov 27, 1998)

• Add new function format_bytes() to display '1K' for '1024', etc. (suggested by Curt Tilmes <curt@ltpmail.gsfc.nasa.gov>)
• Fix bugs in round() and format_picture() when dealing with negative numbers. NOTE: format_picture() now includes at least one extra space in its output for positive numbers. This may present a minor incompatibility issue in some obscure cases.
• Minor documentation updates.

Changes for version 1.30 (Oct 31, 1998)

• Fix several major bugs, including the POSIX-not-required issue, as well as better support for negative values.
• Add setting for default size of decimal area so you don't have to specify the number of digits if it's other than 2.
• Add setting and function to display negative numbers in different formats.
• Add setting to force trailing 0's in the decimal portion to fill out the number of digits required.
• Fix problem where 0's inside format_picture()'s output were being replaced with spaces.
• Add 0 before decimal point if number is between -1 and 1.
• Fix errors with supposedly-optional POSIX
• From: Yair Lenga <yair@bpa1.sbi.com> Suggested adding controls to pad out result of format_number with zeroes as well as the ability to present negative numbers with parentheses. Provided a patch which was useful in constructing a solution.
• Add test for defined() from patch by IMAZU Hideyo <himazu@ms.com>
• From: "Joseph Norton" <namaste1_@hotmail.com> Bugs in format_number(): processed negative numbers incorrectly, and lacked the zero before the decimal point if number is between 0 and 1.

Changes for version 1.20 (Aug 31, 1998)

• Make POSIX no longer required (users on MicroSoft systems sometimes don't have it); uses US defaults if no POSIX.pm found.
• Add new optional third argument to format_number() to add trailing zeroes.

Changes for version 1.12

• Remove 'use of undefined value' warnings when used with perl -w

Changes for version 1.10 (Nov 21, 1997)

• Add Locale support to set the default values for $THOUSANDS_SEP, $DECIMAL_SEP, and $CURRENCY based on the user's locale.
• Add object oriented interface.
• NOTE: Some aspects of the API have changed. Please reread the documentation carefully if you used 1.0 previously!!!
