Enum rust_decimal::RoundingStrategy [−][src]
pub enum RoundingStrategy { MidpointNearestEven, MidpointAwayFromZero, MidpointTowardZero, ToZero, AwayFromZero, ToNegativeInfinity, ToPositiveInfinity, BankersRounding, RoundHalfUp, RoundHalfDown, RoundDown, RoundUp, }
RoundingStrategy
represents the different rounding strategies that can be used by
round_dp_with_strategy
.
Variants
When a number is halfway between two others, it is rounded toward the nearest even number. Also known as “Bankers Rounding”. e.g. 6.5 -> 6, 7.5 -> 8
When a number is halfway between two others, it is rounded toward the nearest number that is away from zero. e.g. 6.4 -> 6, 6.5 -> 7, -6.5 -> -7
When a number is halfway between two others, it is rounded toward the nearest number that is toward zero. e.g. 6.4 -> 6, 6.5 -> 7, -6.5 -> -6
The number is always rounded toward zero. e.g. -6.8 -> -6, 6.8 -> 6
The number is always rounded away from zero. e.g. -6.8 -> -7, 6.8 -> 7
The number is always rounded towards negative infinity. e.g. 6.8 -> 6, -6.8 -> -7
The number is always rounded towards positive infinity. e.g. 6.8 -> 7, -6.8 -> -6
Please use RoundingStrategy::MidpointNearestEven instead
When a number is halfway between two others, it is rounded toward the nearest even number. e.g. 6.5 -> 6, 7.5 -> 8
Please use RoundingStrategy::MidpointAwayFromZero instead
Rounds up if the value >= 5, otherwise rounds down, e.g. 6.5 -> 7
Please use RoundingStrategy::MidpointTowardZero instead
Rounds down if the value =< 5, otherwise rounds up, e.g. 6.5 -> 6, 6.51 -> 7 1.4999999 -> 1
Please use RoundingStrategy::ToZero instead
Always round down.
Please use RoundingStrategy::AwayFromZero instead
Always round up.
