1 Decimal Place Without Rounding

[andy75180]

Hi ya,

 

If I have a float number of say 3.478399 How can I reduce the number to 1 decimal place without rounding?

 

I've tried it will sprintf, but it rounds the 4 to a 5 which I want to avoid.

 

$float_number = 3.478399;
$new_float_number = sprintf ("%0.1f",$float_number);

 

 

Output returns  3.5 when really I need it to be 3.4

 

Any help anyone?

<php
function expl($str) {
$str = explode(".", $str);
$decimal = substr($str[1], 0, 1);
return $str[0].'.'.$decimal;
}
echo expl(3.478399);
?>

 

This is probably the hardest way to do it
