PHP function

hi,all
In PHP, are there any functions which can convert 66.666666% to 66.6%?

Cheers

$var = 66.6666666;
$newvar = round($var, 1);
echo $newvar;
//output 66.6? Right?

Regards

Johan

Damn, I was wrong, it will get output 66.7...
But I you just want to cut of the last parameters you can do something like this (eg. 6.79 => 6.7)

$var = 34.98554;
$arr_var = explode(".", $var);
$AfterTheDot = substr($arr_var[1], 0, 1);
$newvar = $arr_var.".".$AfterTheDot;
echo $newvar;

//output 34,9

Regards,

Use floor() function:

$x=66.6666666;
$y=(floor($x*10))/10;

That's it, I suppose. Should work.

Try to use sprintf

thanks everyone

Unfortunately all number formatting functions seem to round-up.

If it's only for display:

$a = sprintf("%6.3f",66.666666);
echo substr($a, 0, strlen($a)-1);

this simply changes the format to 66.667, and chops off the last digit.

Not nice, but it works.
