I want to round up to the next even whole number, with php.
Example:
- if 71 -> round up to 72
- if 33.1 -> round up to 34
- if 20.8 -> round up to 22
I want to round up to the next even whole number, with php.
Example:
$num = ceil($input); // Round up decimals to an integer
if($num % 2 == 1) $num++; // If odd, add one
Test cases:
$tests = ['71' => '72', '33.1' => '34', '20.8' => '22'];
foreach($tests as $test => $expected) {
$num = ceil($test);
if($num % 2 == 1) $num++;
echo "Expected: $expected, Actual: $num
";
}
Expected: 72, Actual: 72
Expected: 34, Actual: 34
Expected: 22, Actual: 22
