script modifying float values gives integer

[frankienrg]

I know I may sound like a nab, but here I go:

 

$ric=10;
$price=$price+($price/$ric);

 

Basically I want to add a 10% to the price value

 

this is inside a "for", and price values is taken from a csv file.

 

Said value is for example:

$price=4,36

 

after the script takes place, the value goes to:

$price=4796

 

While i aimed to obtain 4,80 (a 2 precision float).

 

Can anyone help me? It's the first time I mess with float numbers.

 

EDIT: Or at least direct me to a more efficient way to apply % on doubles, while preserving the original precision

nevermind, found it

 

	$prezzo = number_format($prezzo, 2, '.', '');
	$prezzo = $prezzo+number_format(($prezzo/$ricarico), 2, '.', '');
