✦ Tips

  • ROUNDDOWN behaves like ROUND, except that it always rounds a number down.
  • If num_digits is greater than 0 (zero), then number is rounded down to the specified number of decimal places.
  • If num_digits is 0, then number is rounded down to the nearest integer.
  • If num_digits is less than 0, then number is rounded down to the left of the decimal point.
