Range

A range of values

A few recipe requirements such as Time or Position need a range to function properly.

The range can be an unique number (in that case just specify it) or a range of values starting from negative infinity (-2147483648) to positive infinity (2147483647).

Several ranges can also be specified, in that case the tested value must match at least one of the specified range to pass.

Syntax :

The range must be specified with the following syntax :

1. Start with [ (lower bound included) or ( (lower bound excluded).

2. A number which will be the lower bound of the range, or nothing if you want no lower bound.

3. A , to separate the lower bound from the upper bound.

4. A number which will be the upper bound of the range, or nothing if you want no upper bound.

5. End with ] (upper bound included) or ) (upper bound excluded).

6. If you want to specify another range

Special cases :

• Use "" or "*" to make a range that accept any values.

• Use "1" to make a range that accept only the number 1.

Examples :

Some range examples are:

Spec	Description
"1"	Accept only 1
"[1,42)"	Accept 1 (included) to 42 (not included)
"[1,42]"	Accept 1 to 42 (both included)
"[1,)"	Accept 1 and higher
"(,1],[42,)"	Accept up to 1 (included) and 42 or higher
