Properties

ROUND_CEILING

number

Constant for the rounding mode:

Rounds a number towards positive infinity. If the decimal number is positive, the behavior is the same as for ROUND_UP, if it is negative, it is the same as ROUND_DOWN.

The value is never reduced.

---

ROUND_DOWN

number

Constant for the rounding mode:

Rounds a number towards zero.

---

ROUND_FLOOR

number

Constant for the rounding mode:

Rounds a number towards negative infinity.

---

ROUND_HALF_DOWN

number

Constant for the rounding mode:

The number is rounded towards the "next neighbor", except if both are equidistant. In this case, it is rounded towards zero.

---

ROUND_HALF_EVEN

number

Constant for the rounding mode:

The number is rounded towards the "next neighbor", except if both are equidistant. In this case, it is rounded towards the even neighbor.

---

ROUND_HALF_UP

number

Constant for the rounding mode:

The number is rounded towards the "next neighbor", except if both are equidistant.

In this case, it is rounded towards up (opposite direction from zero).

---

ROUND_UP

number

Constant for the rounding mode:

Rounds a number up. The digit before the discarded digit is always rounded up (unequal to zero).

This rounding mode will never decrease the value of the digit rounded.
