Value range - "value_range"
For numerical attributes, the permissible domain is specified in the REXS database in interval notation. The following convention applies:
Opening bracket: interval lower limit
Closing bracket: interval upper limit
Also:
Parentheses: limit is not included in the interval (< / >)
Brackets: limit is included in the interval (<= / >=)
Table 1. Examples
for value ranges
Value range | Notation |
|---|---|
0 < value | (0; ∞) |
0 <= value < 1 | [0; 1) |
-90 <= value <= 90 | [-90;90] |
indefinite | (-∞; ∞) |
The value range for enum attributes is also included in the REXS database.
