Keeping two scale or decimal digits of a values without rounding it

16/10/2015 - PHP

Sometimes you want to avoid rounding up or down and always have two scale/decimal points for the given value. If you use number_format, money_format, round, so on. you will get different results. To solve this issue, you can use example below.


Function


function formatNumber($value)
{
    return number_format(floor($value * 100) / 100, 2);
}

$array = [
	0,
	0.00,
	0.4,
	0.5,
	1.0,
	1.9,
	1.99,
	1.999,
	1.444,
	1234567,
	"1.",
	"1,6"
];

foreach ($array as $value) {
	echo formatNumber($value).PHP_EOL;
}

Result
