**''<Integer>''**

''<Integer> == [[simple|<Simple>]]'' || ''<IntInterval>'' || ''<IntSelection>''

''<IntInterval> == [[simple|<Simple>]] - [[simple|<Simple>]]''

''<IntSelection> == <IntSelItem>'' || ''<IntSelection> | <IntSelItem>''

''<IntSelItem> == [[simple|<Simple>]]'' || ''[[simple|<Simple>]] : [[simple|<Simple>]]''

''<Integer>'' is a whole number which can be input directly or, alternatively, can be selected by a random number generator.

There are two methods by which a random number can be generated:

  * **Interval:** An interval is input by two ''<Simple>'' values separated by a hyphen (-). All of the values in the interval (that is, the beginning number and the final number as well as every number in between) have the same likelihood of being selected. 
  * **Selection:** A selection consists of numbers input by the user, separated by the | sign.  All of the numbers have an equal probability of being selected.  

The probability that a number will be selected can be customized so that probabilities can be assigned to numbers.  The probabilities can be input before the number separated from the number with a colon ( '':''). The probability value is itself a ''<Simple>'' number. 

It is possible to mix expressions: some numbers can have assigned probabilities in the same selection as numbers without probability assignments.  In such a case, numbers not assigned an explicit probability take the implicit probability of 1.

Examples:

|**''4''**  |Simple number.  Its value is always 4.|

|**''2-5''**  |Interval.  The value corresponds to a random selection between 2, 3, 4 and 5. All 4  choices have an equal probability of 25%.|

|**''2|5|7''**  |Selection.  The value corresponds to a random selection between 2, 5 and 7. All three choices have a probability of 33%.|

|**''3:2|4|5:6|8''**  |Selection. The value corresponds to a random selection between 2, 4, 6 and 8. The 2 appears with a probability of 30%, the 4 with a probability of 10%, the 6 with a probability of 50% and the 8 with a probability of 10%.|
