Reference Page: Comparison Rules

Automatic Comparison Rules

Relationship: One-to-Many / Rule: Is Value In Range

Definitions

Supported data types: String, Number, Date
Supported data structures: Scalar, Vector

Comparison of values of different data types always returns False.
Comparison of values of unsupported data types always returns False.

Scalar data structure is presented by any single value.
Vector data structure is presented by a set (un-ordered array) of values of the same type. Externally, Set is defined as a comma-separated sequence (might be encoded in string). Internally, Set is transformed into array to optimize performance.

The value is in range if it is greater (equal or greater for inclusive comparison) then a minimal value member of a set, and is less (equal or less for inclusive comparison) then a maximal value member of a set.
Example: 5 is in range of a set {2,10, 5, -1, 20}

Data type: String

Strings are compared based on total length and encoding of each character.

Two strings are considered equal if they have equal length (same number of characters) AND all characters, compared one by one, were equal.

Data type: Number

Numeric values are considered equal if there is no difference (near-zero-difference) between them (matters for floating point numbers with precision loss).

Data type: Date

Date/time values are compared per component values: Year, Month, Day, Hour, Second. Two dates are considered equal if there is zero seconds difference between them.

Implementation

  boolRC = isSameFormat1N(sActualValue, dvArray, sFormat)

  Else
    boolRC = isValueGreater(sActualValue, RangeMin, sFormat)
    boolRC = boolRC AND isValueLess(sActualValue, RangeMax, sFormat)
