Question

I’m working with currencies so for example –

5 is OK as it is interpreted as 5.00. But 5.005 is not as it has too many digits after the point.

How can I restrict the amount of digits and show an error if there’s too many?

Thanks

Answer 1

$x = '5.005'; // declare as string to avoid floating point errors
$parts = explode('.', $x);
if (strlen($parts[1]) > 2) {
   die("Too many digits");
}
