The ROUNDDOWN function in Google Sheets is used to round a number down to the nearest integer. For example, if you enter the number 9.5 into the function, it will return the number 9.
The syntax of ROUNDDOWN in Google Sheets is to use the function name followed by the number of decimal places to round to. For example, the syntax for rounding down to the nearest whole number is ROUNDDOWN(number, 0).
One way to use the ROUNDDOWN function in Google Sheets is to round a number down to the nearest whole number. For example, the following formula would round the number 5.5 down to 5: =ROUNDDOWN(5.5, 0)
Another way to use the ROUNDDOWN function is to round a number down to a specific number of decimal places. For example, the following formula would round the number 5.5 down to 2 decimal places: =ROUNDDOWN(5.5, 2)
The ROUNDDOWN function can also be used in combination with the IF function to create a conditional rounding rule. For example, the following formula would round the number 5.5 up to 6 if it is greater than 5, and round it down to 5 if it is less than or equal to 5: =IF(5.5>5, 6, 5)
