Decimal Attributes

Attribute type id	Type specific restriction parameters
decimal	minValue: Minimum decimal value (inclusive)
	maxValue: Maximum decimal value (inclusive)
	minDecimal: The minimum length (inclusive) of integer part (digits left of decimal point)
	maxDecimal: The maximum length (inclusive) of integer part (digits left of decimal point)
	minFraction: The minimum length (inclusive) of fractional part (digit right of decimal point)
	maxFraction: The maximum length (inclusive) of fractional part (digit right of decimal point)
	maxDigits: Maximum length of decimal and fraction part (without “.” - inclusive)
	patterns: List of patters that the value must match (Java Pattern). Values has to match all the patters. Pattern is only matched against the attribute value - without unit.
	units: List of possible units to use (units have to be defined in `unitsOfMeasure` section of datastandard)

📘
All restrictions are validated in provided order.
Attribute validation will fail on the first unfulfilled restriction.

Code Examples:

{
  "id" : "WRENCH_HEAD_SIZE_MM",
  "name" : "Wrench Head Size (mm)",
  "type" : {
    "id" : "decimal",
    "restriction" : {
      "parameters" : {
        "minValue" : "0.5",
        "minDecimal" : "0",
        "maxValue" : "99",
        "maxFraction" : "1",
        "maxDecimal" : "2",
        "maxDigits" : "3",
        "minFraction" : "0"
      }
    }
  }
}
