Question

I have this PHP code:

<?php
    $float = "1,99";
    echo "<p>$float<br>";
    $float = floatval($float); // Without this line number_format throws a notice "A non well formed numeric value encountered" / (float) $float leads to the same output
    $val = number_format($float, 2,'.', ',');
    echo "$float</p>";
?>

Why does it return 1? Don’t get that.

And: yes, there is a sense in converting 1,99 to 1,99 😉

Thanks for advise…

Answer 1

floatval recognizes the comma (,) as a character and not as a number, so it cuts off everything that comes after it. In this case, that’s the 99. Please use a dot (.) instead of a comma (,) and it will probably work.

Example floatval (source: http://php.net/manual/en/function.floatval.php):

<?php
$var = '122.34343The';
$float_value_of_var = floatval($var);
echo $float_value_of_var; // 122.34343
?>
