Require 2 decimal places

[Anon]

Hello,
I have a PHP script that calculates prices for an item based on customer input. I need to have the displayed numbers to have 2 decimal places. So if the final price was 45 dollars, right now my script shows:
$45

I want it to show:
$45.00

How can I get this to work?

Hi,

I'm in the same boat as you, ra! I'm getting a double variable from MySQL (numbers: 18 or 18.1, for example). I want the numbers to have the decimal at all times though. This is the code I'm using:

$num1 = 458;
settype($num1,"double");

print $num1; //Prints "458"

I can't seem to get the ".xx" decimal at the end. Am I using the wrong function??

Please help.

Ilir.

Got it!

I used printf() and got my thing working. Here's how you do it:

$num1 = 43;
printf ("%.2f",$num1);
//prints:
//43.00

Note: the "2f" part tells PHP to have the float-type variable display 2 decimal places, which means that you can change that number to whatever you want.

Hope this helps!

Use number_format()

$y = "1200";
$x = number_format($y,2);
echo "$x";

gives: 1,200.00

This will not only give you the desired 2 decimal places but a thousands comma as well. Nice 🙂
