php - number_format only if not zero

Solution:

ini_set("precision", 8); /* low enough; eventually if needed */
var_dump((string)round($float, 1));
Copy code

this should do the task

Solution:

use in the following manner.

$x = "99.44";  // example value
$y =  number_format((float)$x, 1, '.', '');
echo str_replace(".0","",$y);

Solution:

I prefer this way:

$num = 100.1;
echo (floor($num) == $num) ? $num : number_format($num,1);

Solution:

$rounded = (!is_int($number)) ? round($number, 1) : round($number);

I have tested the above with your sample data and the outputs are as follows:

100.00 > 100
99.45 > 99.5
99.44 > 99.4
11.30 > 11.3
2.00 > 2
11.02 > 11
13.05 > 13
