# Ceiling online calculator: Calculate the smallest integer greater than a given number

You can calculate the ceiling value of a given number inputting the ceil command and several numbers in the form above. For example, if you want the ceiling value of 3.1, paste ceil 3.1 in the form and press the enter key.

ceil 3.1


The result is 4.

ceil 3.1
ceil
(3.1) = 4


4 is the ceiling value of 3.1.　The values in parentheses is what you input and right values are outputs.

The ceiling value is the smallest integer greater than a given number. In this case, 4, 5, 6, 7, ... are bigger than 3.1 and 4 is the smallest of them, so 4 is the ceiling of 3.1. The ceiling function use the symbols like square brakets.

$\lceil 3.1 \rceil = 4$

But some books use ceil() instead of it.

## Multiple ceiling values

This online calculator can take several arguments like this.

ceil 3.1 67.4 0.125 -0.4


The result is here.

ceil 3.1 67.4 0.125 -0.4
ceil
(3.1) = 4
(67.4) = 68
(0.125) = 1
(-0.4) = 0


The ceiling of 3.1, 67.4, 0.125, -0.4 are 4, 68, 1, 0 respectively.
