Fixed movedec. Now works with any number. Also added which way to move decimal. Default is left.
function movedec ($num , $move ,$way){
if($way == 'left'){
$left = ereg_replace("([0-9]+)([\.])([0-9]+)","\\1",$num);
$right = ereg_replace("([0-9]+)([\.])([0-9]+)","\\3",$num);
while(strlen($left) <= $move){
$left = '0'.$left;
}
$left = strrev($left);
$left = ereg_replace("([0-9]{".$move."})([0-9]+)","\\1.\\2",$left);
$left = strrev($left);
$num = $left.$right;
}
else{
$left = ereg_replace("([0-9]+)([\.])([0-9]+)","\\1",$num);
$right = ereg_replace("([0-9]+)([\.])([0-9]+)","\\3",$num);
$right = strrev($right);
while(strlen($right) <= $move){
$right = '0'.$right;
}
$right = strrev($right);
$right = ereg_replace("([0-9]{".$move."})([0-9]+)","\\1.\\2",$right);
$num = $left.$right;
}
return $num;
}
