ROUND explained
Simply put, the ROUND function enables us to round numbers. That's it.
So if we had the following number:
I could round it to 2 decimal places using the ROUND function:
The ROUND function allows us to round a given number to a specific decimal place.
Coding a ROUND function
Let's first check out the ROUND function template, and then apply it.
=ROUND(number, num_digits)
In the above situation, we wanted to round 5.6324...
=ROUND(5.6324, num_digits)
...to 2 decimal places.
=ROUND(5.6324, 2)
When we plug this into Excel, we get the same output as we got on the calculator!
It's important to remember...
The num_digits argument doesn't represent the total number of digits, it represents the number of digits after the decimal point!
For example, if we wanted to round to a whole number, all we'd need to do is place a "0" as the second argument, signifying we want 0 digits after the decimal point.
Practice problem
Round the number 17.91635 to 3 decimal places.
=ROUND(B1, B2)
Answer: 17.916
Next, let's learn the difference between the WEEKDAY and WORKDAY functions and how we can use them.
