Keeping this in consideration, what does 0 decimal places mean?
If num_digits is greater than 0 (zero), thennumber is rounded to the specified number of decimal places.If num_digits is less than 0, the number is rounded to theleft of the decimal point.
Also Know, what counts as a decimal place? The units place value is always the first numberto the left of the decimal.
