Question

math. ceil(-5.1)
math. floor(-5.1) ​

Answer 1

Question :

Math.ceil(-5.1)

Math.floor(-5.1)

Output :

Math.ceil(-5.1) = -5.0

Math.floor(-5.1) = -6.0

Answer 2

The math.ceil(x) function returns the smallest integer greater than or equal to x.

So, math.ceil(-5.1) would return -5, because -5 is the smallest integer that is greater than or equal to -5.1.

On the other hand, the math.floor(x) function returns the largest integer less than or equal to x.

So, math.floor(-5.1) would return -6, because -6 is the largest integer that is less than or equal to -5.1.

math.ceil(x):

The ceil() function rounds up a given number x to the nearest integer greater than or equal to x.

For example, math.ceil(4.2) would return 5, since 5 is the smallest integer that is greater than or equal to 4.2.

Similarly, math.ceil(-3.8) would return -3, since -3 is the smallest integer that is greater than or equal to -3.8.

This function is useful when you want to ensure that a value is rounded up to the nearest integer, even if it has a decimal component.

math.floor(x):

The floor() function rounds down a given number x to the nearest integer less than or equal to x.

For example, math.floor(6.7) would return 6, since 6 is the largest integer that is less than or equal to 6.7.

Similarly, math.floor(-2.3) would return -3, since -3 is the largest integer that is less than or equal to -2.3.

This function is useful when you want to ensure that a value is rounded down to the nearest integer, even if it has a decimal component.

Both of these functions are useful for various mathematical operations where you need to round a value up or down to the nearest integer, and they are commonly used in programming languages like Python.
