Rounding numbers - PHP Development

Hi All! Maybe someone could help me pls? I'm really average at PHP, and right now I'm trying to figure out how to round a number to only two figures after a decimal point so that for example, 2.136 became simply 2.14. A quick browse of PHP.net brought up the 'round' command, but when I tried implementing it in my only hamfisted way as below, the results were not at all right! Could someone show me what I have goofed up on pls? <? $number = 12.566 ; $rounded = round($number, -2); echo $number ; echo $rounded ; ?> THANKS!! ...
