How to use the ROUNDUP function

The ROUNDUP function is similar to the ROUND function. The only difference is that the ROUNDUP function will always round any numbers between 1 and 9 up.

The ROUNDUP function can round both to the left and right of a decimal point.

When num_digits is greater than 0,  the value is rounded up to the right of the decimal point using the given number of decimal places.

When num_digits is less than 0, the original number is rounded up to the left-hand side of the decimal point.

When num_digits = 0,  the original number is rounded up to the nearest whole number.
