Formulas / ROUNDDOWN
Round down to a specified number of digits.
`=ROUNDDOWN(number,num_digits)`
• number - the number to truncate
• num_digits - [REQUIRED] the place where to round number

## Examples

• `=ROUNDDOWN(3.9,0)` rounds 3.9 down to the nearest whole number, which is 3.

• `=ROUNDDOWN(A1,1)` rounds down to the nearest decimal place. For example, if A1 is 3.75, the result would be 3.7.

• `=ROUNDDOWN(A1,2)` rounds down to the nearest two decimal places. For example, if A1 is 3.753, the result would be 3.75.

• `=ROUNDDOWN(A1,0)` rounds down to the nearest one. For example, if A1 is 3.4, the result would be 3.

• `=ROUNDDOWN(A1,-1)` rounds down to the nearest ten. For example, if A1 is 23.4, the result would be 20.
