Python math ceil function<\/strong> is one of many functions provided by Python\u2019s math<\/code> module. In this article, we\u2019ll see how to use it through examples.<\/p>\n\n\n\n

Other similar functions include the floor()<\/code> function I wrote about in this article<\/a> and the round()<\/code> function.<\/p>\n\n\n\n

Python math ceil function explained<\/h2>\n\n\n\n

The ceil()<\/code> function calculates the smallest integer greater than or equal to the number x<\/code>.<\/strong> In other words, it rounds the number x<\/code> up to the nearest integer value as shown in the figure below.<\/p>\n\n\n\n

\"Example<\/figure>\n\n\n\n

The syntax is as follows:<\/p>\n\n\n\n

math.ceil(x)<\/pre>\n\n\n\n
where x<\/code> is the value you want to apply ceiling to.<\/p>\n\n\n\n
Below you can find the example of the ceil()<\/code> function usage.<\/p>\n\n\n\n
>>> import math\n>>> math.ceil(3.14)\n4<\/pre>\n\n\n\n
To apply the ceiling operation on a particular number or mathematical expression, first import Python\u2019s math<\/code> module. Then pass the number to the ceil()<\/code> function as the first argument. As a result, you\u2019ll get the nearest integer value greater than or equal to the passed number.<\/strong><\/p>\n\n\n\n
NOTE<\/strong> - Python 2 returns a ceil()<\/strong> function result as a floating point value (float). Python 3 returns it as an integer value (int).<\/pre>\n\n\n\n
You can see a few examples of using the Python ceil()<\/code> method below.<\/p>\n\n\n\n
x<\/strong><\/th>math.ceil(x)<\/strong><\/th><\/tr><\/thead>
3.14<\/td>4<\/td><\/tr>
4<\/td>4<\/td><\/tr>
2.99999999<\/td>3<\/td><\/tr>
-3.14<\/td>-3<\/td><\/tr>
-4<\/td>-4<\/td><\/tr>
-2.99999999<\/td>-2<\/td><\/tr>
math.inf<\/td>OverflowError<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
Notice that the OverflowError<\/code> was raised when math.inf<\/code> (Infinity) value was passed to the ceil()<\/code> function. This happened because the math.inf<\/code> (float value) was attempted to convert to an int<\/strong> value which caused an overflow.<\/p>\n\n\n\n
Ceil division in Python<\/h3>\n\n\n\n
Unlike the floor division that is supported by a special \/\/<\/code> operator, there\u2019s no special operator for a ceil division. But there are two ways how you can achieve the same result.<\/p>\n\n\n\n
