How to use the rounding function in MATLAB

In MATLAB, you can use the following function to round a number:

1. Use the floor function to return the largest integer less than or equal to x, effectively rounding down.
2. For example:
3. Assign the value of 3.5 to x, then round down x and assign it to y, so y will be 3.
4. ceil(x): Returns the smallest integer greater than or equal to x, also known as rounding up.
5. For example:
6. x is equal to 3.5
   y is equal to the smallest integer greater than or equal to x, which would be 4.
7. round(x): returns the nearest integer to x.
8. For example:
9. The variable x is equal to 3.5 and when rounded, y equals 4.
10. fix(x): returns the largest integer less than or equal to x, but if x is negative, it returns the smallest integer greater than or equal to x.
11. For example,

    I will be arriving around 8 pm.

12. x is equal to 3.5;
    y is set to the whole number nearest to x. Therefore, y is equal to 3.

    In the case where x is equal to -3.5;
    y is set to the whole number nearest to x. Therefore, y is equal to -3.

These rounding functions can be applied to different types of variables, such as scalars, vectors, and matrices.
