Any php function to to drop decimal part if its zero

Question

javascript Number function is handy when dropping undesired zero if decimal part is zero e.g

Number(2.00)

2

Is there such function in php or any alternative

Answer 1

I think this works that way by default in PHP. If you use proper number type like float or double.

If you're using string then you need to map

$a = '2.00';
echo (float)$a; // 2

Example of using float

$a = 2.00;
echo $a; //2

or

2.00 + 0; //2

If you want to format the number to show decimal part 2.00 you need to use number_format function (http://php.net/manual/en/function.number-format.php)

$a = 2.00
echo number_format($a, 2); // 2.00

Answer 2

you can use intval() or any roundoff function

$_float = 1.9020441;
$_float = explode(".", $_float);
echo strlen($_float[1]);`

Answer 3

You can achieve this by adding zero ... for example

echo "Result " . (2.00 + 0) . "\n";

Result 2

Answer 4

you can use floatval()

echo floatval('2.00'); //2
echo floatval('2.23'); //2.23
