enum Number::RoundingMode
Overview
Specifies rounding behaviour for numerical operations capable of discarding precision.
Defined in:
number.crEnum Members
-
TIES_EVEN =
0 -
Rounds towards the nearest integer. If both neighboring integers are equidistant, rounds towards the even neighbor (Banker's rounding).
-
TIES_AWAY =
1 -
Rounds towards the nearest integer. If both neighboring integers are equidistant, rounds away from zero.
-
TO_ZERO =
2 -
Rounds towards zero (truncate).
-
TO_POSITIVE =
3 -
Rounds towards positive infinity (ceil).
-
TO_NEGATIVE =
4 -
Rounds towards negative infinity (floor).
