Multiplying 2 floating points returning 0 ?

$Copies_of_print = 3;
$item_cost = 0.0;
$item_cost = 6.5;

$line_total = $Copies_of_print * $item_cost;
print($line_total);

gives 0, instead of 19.5

do i need to type cast?

Thanks!

 

Hello,

I copied the code you posted and it worked.

<?php

$Copies_of_print = 3;
$item_cost = 0.0;
$item_cost = 6.5;

$line_total = $Copies_of_print * $item_cost;
print($line_total);

?>

Code (markup):

shows 19.5. I tired it in PHP 4 and PHP 5

 

i also tried this code and it shows 19.5.
there is no reason of showing 0
you assigned 6.5 to $item_cost last so it does not have the value 0
