How do I use the ROUNDUP function in Excel?

The ROUNDUP function in Excel is a mathematical function that is used to round up a number to a specified number of decimal places. This function is useful in situations where you need to round up numbers to the nearest whole number or to a specific decimal place.

The syntax for the ROUNDUP function is as follows:

=ROUNDUP(number, num_digits)

The number argument is the number you want to round up, and the num_digits argument is the number of decimal places to which you want to round up.

For example, if you have the number 3.14159 in cell A1 and you want to round it up to two decimal places, you would use the following formula:

=ROUNDUP(A1, 2)

The result would be 3.15.

You can also use negative values for the num_digits argument to round up to the nearest 10, 100, or 1000. For example, if you have the number 1234 in cell A1 and you want to round it up to the nearest 100, you would use the following formula:

=ROUNDUP(A1, -2)

The result would be 1300.

Overall, the ROUNDUP function is a powerful tool for rounding up numbers in Excel to a specified number of decimal places or to the nearest 10, 100, or 1000.
