RoundingRule

Parameter Name	Type	Description
`CountryCode`	String	2-char ISO country code
`CurrencyCode`	String	3-char ISO currency code
`RoundingRanges`	List of `RoundingRange`	List of decimal ranges and their respective rounding behavior.
`RoundingRuleId`	Decimal	Rule identifier denoting the respective Rounding Rule on the Global‑e side. This value must be further specified when calling `SaveProductsList` and `SendCart` methods

RoundingRange

Parameter Name	Type	Description
`From`	Decimal	A decimal value of the range start, exclusive of the `From` value itself. If a range must start from 0 inclusive, the `From` value must be set to a negative number.
`LowerTarget`	Decimal	A decimal value used to calculate the target rounded value, for the numbers less than the `Threshold`, according to the defined `Range` behavior. If the `LowerTarget` value violates the `MaxDecimalPlaces` setting for the respective currency, it must be truncated as described in the “Important Notices” below.
`RangeBehavior`	Decimal	One of the possible values of `RangeBehaviors` enumeration defined below which is designed to control the way rounding range is handled. The range behavior is applied to `Threshold`, `LowerTarget`, `UpperTarget` and `Exceptions` in the `RoundingExceptions` list.
`RoundingExceptions`	List of `RoundingException`	List of decimal values used to calculate the exceptions for rounding, i.e. values not to apply rounding for. `RangeBehaviors` enumeration: see Table 1 and Table 2.
`TargetBehaviorHelperValue`	Decimal	A decimal value required for the “nearest target” and “relative whole target” behavior.
`Threshold`	Decimal	A decimal value used to split the range so that the values less than the threshold would be rounded to the Lower target, and values greater than or equal to the threshold would be rounded to the Upper target. For the "Absolute target," the threshold range is an absolute value. Other Ranges are Relative values. See the absolute target in Rounding Range for more information. RoundingRange
`To`	Decimal	A decimal value of the range end, inclusive.
`UpperTarget`	Decimal	A decimal value used to calculate the target rounded value, for the numbers greater than or equal to the Threshold, according to the defined Range behavior. If the `UpperTarget` value violates the `MaxDecimalPlaces` setting for the respective currency, it must be truncated as described in the “Important Notices” below.

Table 1: RoundingException

List of decimal values used to calculate the exceptions for rounding, i.e. values not to apply rounding for.

RangeBehaviors enumeration:

RangeBehaviors Option Value	Name	Description
1	Absolute target	In this behavior all the values within the specified range (`LowerTarget, UpperTarget, Threshold and RoundingExceptions`) denote the values themselves as is, without the need for any additional math operations. Getting rounding result (R) for the source number (S) must be implemented as follows: If (S = Exceptionn) then R = Exceptionn If (S < Threshold) then R = LowerTarget If (S >= Threshold) then R = UpperTarget
2	Relative Decimal target	In this behavior all the values within the specified range (`LowerTarget, UpperTarget, Threshold and RoundingExceptions`) represent floating point numbers between 0 (inclusive) and 1 (inclusive), used to calculate the respective absolute values, relative to the calculation base (B) as follows: For source number (S): B = whole part of S LowerTarget (absolute): LA = B – 1 + LowerTarget UpperTarget (absolute): UA = B + UpperTarget Threshold (absolute): TA = B + Threshold Exceptionn (absolute): EAn = B + Exceptionn If (S = EAn) then Result (R) = EAn If (S < TA) then R = LA If (S >= TA) then R = UA
3	Relative Whole target	In this behavior LL the values within the specified range (`LowerTarget, UpperTarget, Threshold and RoundingExceptions`) represent non-negative whole numbers, while `TargetBehaviorHelperValue (V)` is used to determine the calculation base (B). V must be a power of 10 (10, 100, 1000, etc.) and denotes the order of magnitude for the range “split” by the Threshold. For example, if Threshold = 9 we need to know if this is 9 out of 10 or 9 out of 100. Getting rounding result (R) for the source number (S) must be implemented as follows: For source number (S): B = S rounded down to the closest multiple of V For example if (S = 56789 and V = 1000) then B = 56000 LowerTarget (absolute): LA = B – V + LowerTarget UpperTarget (absolute): UA = B + UpperTarget Threshold (absolute): TA = B + Threshold Exceptionn (absolute): EAn = B + Exceptionn If (S = EAn) then Result (R) = EAn If (S < TA) then R = LA If (S >= TA) then R = UA
4	Nearest target	In this behavior, `LowerTarget` and `UpperTarget` represent non-negative floating-point numbers, while TargetBehaviorHelperValue (V) is used to determine the calculation base (B). V must be a whole divisor of any power of 10 (5, 10, 25, 50, 100, 250, 500, 1000, etc.). The threshold must be any floating-point number between 0 (inclusive) and V (exclusive). Getting rounding result (R) for the source number (S) must be implemented as follows: For source number (S): B = S rounded down to the closest multiple of V For example, if (S = 123 and V = 5) then B = 120 LowerTarget (absolute): LA = B – 1 + LowerTarget UpperTarget (absolute): UA = B – 1 + V + UpperTarget Threshold (absolute): TA = B + Threshold Exceptionn (absolute): EAn = B + Exceptionn If (S = EAn) then Result (R) = EAn If (S < TA) then R = LA If (S >= TA) then R = UA

Important Notices

If the result of rounding is a negative number, it must be set to zero, for any rounding behavior defined in the table above.

If either LowerTarget or UpperTarget value violates MaxDecimalPlaces setting for the respective currency, this value must be truncated accordingly. For example, if UpperTarget is set to 0.999 for USD, it must be truncated to 0.99 before using in any further calculations.
