[SOLVED] PHP String Trouble ... HMMmmm

[bri0987]

I have a variable that is set by a "Double field" in mysql.

 

For example: In the database the price of a component is set to 45.50

 

If I echo out the var it works fine because of the cents. BUT - The problem is that when I do math on the var with another number (for example 45.50 + 54.50 ) The var will echo 100

 

I need the var to echo 100.00    IF there are no cents (or .00) I need the cents to display. Is there a way to force this.

 

How can I do this.

 

Any ideas, let me know. Thanks.

<?php
$number = 123.10;
$txt = sprintf("With 2 decimals: %1\$.2f",$number);
echo $txt;
?>

There is also number_format()

You can use the bcadd function following is an example

 

$a = "45.50";
$b = "54.50";
print $a+b; //returns 100
print bcadd($a,$b,2); // returns 100.00

if ur doing ur addition in a query u may use the format function....

 

select format((num1 + num2), 2) as sum from tablename

number_format()  <<< This was the best way to do what I needed.

 

Thank all!
