$num = 9.1
$num.ceiling()  //=  10

$num = 3.8
$num.ceiling()  //=  4

$num = -5.7
$num.ceiling()  //= -5

Method	Description	Example
floor	Round down (toward negative infinity)	4.7 → 4
ceiling	Round up (toward positive infinity)	2.3 → 3
toInt	Drop all digits after the decimal point	7.33 → 7
round	Round to a given precision	6.56 → 6.5

Precision

If $precision is greater than zero, it will return a float with the given number of decimal places.

$num = 9.259
$num.ceiling(2)  //=  9.26
