What is 2.738 Round to Two Decimal Places? In the given number 2.738, the digit at the thousandths place is 8, so we will add 1 to the hundredths place digit. So, 3+1=4. Therefore, the value of 2.738 round to two decimal places is 2.74.
Just use %. 2f as the format specifier. This will make the Java printf format a double to two decimal places.
Head to Formulas > Math & Trig, and then choose either the “ROUNDUP” or “ROUNDDOWN” function from the dropdown menu. Enter the number (or cell) you want to round in the “Number” field. Enter the number of digits to which you want to round in the “Num_digits” field.

<?php echo round(3.6451895227869, 2); ?> EDIT Try using this custom function http://www.php.net/manual/en/function.round.php#102641
<?php function round_up ( $value, $precision ) { $pow = pow ( 10, $precision ); return ( ceil ( $pow * $value ) + ceil ( $pow * $value - ceil ( $pow * $value ) ) ) / $pow; } echo round_up(3.63333333333, 2); // 3.64 ?> You want round
round(3.6451895227869, 2, PHP_ROUND_HALF_UP); The second argument is the precision, the flag tells round to always round up (like ceil)
