Rounding decimal number only last two digit PHP

Question

I have to round of only last two digits near 10 in PHP.

For example 0.27777777777778 ->0.30

0.47777777777778 ->0.50

0.57777777777778 ->0.60

Answer 1

$input=0.27777777777778;
$number = number_format(round($input,1),2);
echo $number;

Round your number to 0.3, then use number format to show two decimal points.
