integer to float

[mayada]

Hi,

How can I change an integer value to float with 2 digits after the decimal places, in php.

for example:

i need to change 100 to be 1.00

thanks

So, what about 123 - would that be 1.23? If so:

$number = number_format($number / 100, 2);

I must ask why this sort of formatting is required. If it needs to be 1.00 then why isn't it received as such?

I've tried your code and customised it but it gives me 0.00 rather than 1.00

$number = number_format($number / $_POST['PurchaseAmount'], 2); 

In answer to Chris's question, this is how I recieve the amount from an external system (an online transaction processing system), I have no control over the formatting. The only way they can post it to me is as integer.

Thanks

That's because $number is supposed to be equal to $_POST['PurchaseAmount']. Also, you should check ("sanitize") that PurchaseAmount is a reasonable number, and a number at all.

$pa = $_POST['PurchaseAmount'];
if (!is_numeric($pa)) {
  //error
}
else {
  $pa = number_format($pa / 100, 2);
} 

Dividing by 100 is what turns it from 100 to 1.00 or from 156 to 1.56 etc.

This works now.
