ROUND (rounding function) is a function that rounds a number with more than one decimal place to the number of decimal places
Function syntax: ROUND (which number should be rounded to a few decimal places)
ROUNDUP (the function that retains several digits after the decimal point) means to retain 2 digits after the decimal point of a decimal point. As long as the third digit of the decimal has a value, no matter how much it is (regardless of rounding), then the number of digits after the decimal point after the operation is completed. Both digits must be rounded up by 1.
Function syntax: ROUNDUP (which number should be rounded to the number of decimal places)
ROUNDDOWN (a function that retains several decimal places and rounds off) means to retain 2 decimal places after the decimal point. No matter whether there is a value in the third decimal place, no matter how much it is (regardless of rounding), then the decimal point of the decimal is calculated. The second digit is the original two digits after the decimal point.
