My PHP manual (from a Debian package) has the following note on the page for round(): Caution When rounding on exact halves round() rounds down on evens and up on odds. If you want to always force it in one direction on a .5 (or .05 in your case) add or substract a tiny fuzz factor. The reason behind rounding half the values down and the other half up is to avoid the classical banking problem where if you always rounded down you would be stealing money from your customers, or if you always rounded up you would end up over time losing money. By averaging it out through evens and odds you statistically break even. -- Martin Geisler My GnuPG Key: 0xF7F6B57B PHP EXIF Library | PhpWeather | PhpShell http://pel.sf.net/ | http://phpweather.net/ | http://gimpster.com/ Read/write EXIF data | Show current weather | A shell in a browser -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
