math.ceiling()

math.ceil() is a function in the math module of Python that returns the smallest integer greater than or equal to a given value. It takes one argument, which is a numeric value (integer or float), and returns an integer value.

For example, math.ceil(4.2) returns 5, math.ceil(5.9) returns 6, math.ceil(-4.2) returns -4, and math.ceil(-5.9) returns -5.

This function is commonly used in mathematical operations where we need to round up a value to the nearest integer.
