[SOLVED] remove trailings 00

[AnotherQuestion]

I would like to remove all characters after 2decimal places eg

 

34.0000 would become 34.00

32.9800 would become 32.98

and 7.7000 would become 7.70

 

cant find any reference to on how to do it.

$haystack = '34.0000';
$point = strpos($haystack, '.'); //Search for decimal.
$needle = substr($haystack, 0, $point + 3);  // Only 
echo $needle;

number_format()

Yes, number_format() is what you want.

 

$original = 12.3456789;
$two_decimal = number_format($original, 2);
//Output: 12.35

 

It will also have the effect of increasing the value to two decimals if less than two. In addition, it will round the value to two decimals if needed.

thanks bundyxc your method worked.

 

final code used was

<?php $InvTotal = $row_RSInvoiceHeader['Invoice_Total'];
$point = strpos($InvTotal, '.');
$InvTotalSum = substr($InvTotal, 0, $point + 3); ?>
		 <?php echo $InvTotalSum; ?>

Ok, you do realize that there is a built-in function within PHP to do exactly what you asked for which Mark Baker first suggested, right? But instead you decide to build a customer function for something PHP already does. Brilliant! 

 

You could replce those four lines of code with just this

echo number_format($row_RSInvoiceHeader['Invoice_Total'], 2);

I didn't even think of that function, but I recommend it more than a ghetto handmade function.
