[SOLVED] PHP Arithmetic and Decimal points

[Omzy]

$price=250.00;

$quantity=2;

 

$total=$price*$quantity;

echo $total; //outputs 500

 

I want it to output 500.00

[mikesta707]

use number_format()

 

$price=250.00;
$quantity=2;

$total=number_format($price*$quantity, 2);
echo $total; //outputs 500.00

I'm now trying to add up values to get a subtotal:

 

 
$subtotal=0;

foreach($_SESSION as $value)
{
$total=number_format($value[2]*$value[3], 2);

$subtotal=number_format($subtotal+$total, 2);
}

echo $subtotal;

 

But this does not always display the correct value for $subtotal

[Omzy]

Anyone?

Use number_format just before echo. Until then just do your math without worrying about decimals.

 

$subtotal=0;

foreach($_SESSION as $value)
{
$total=$value[2]*$value[3];

$subtotal=$subtotal+$total;
}

echo number_format($subtotal,2);
