<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%. |
