[snip] I am dividing a number by another number and printing the result to the screen. How can I ensure that the number is rounded up to 2 decimal places? [/snip]
Why others never test these things I'll never know...but here is a small test you can run.... <?php /* ** rounding / number format test */ $number = 12.2345; echo number_format($number, 4, '', ',')."\n"; echo number_format($number, 3, '', ',')."\n"; echo number_format($number, 2, '', ',')."\n"; echo "\n"; echo round($number, 4)."\n"; echo round($number, 3)."\n"; echo round($number, 2)."\n"; ?> The results .... 12.2345 12.235 12.23 12.2345 12.235 12.23 Interesting, no? It would appear that under PHP4.2.1 on a test server that number_format() exhibits the same behaviour as round(). Have a pleasant and productive day. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
