Template:Random number
From Dolphin Emulator Wiki
[edit] [ ] Template documentation
This template generates a pseudo-random integer between 0 and count-1.
Usage
- {{Rand|count|seed|prime}}
- All parameters are optional and have default values. They must be integers.
- The default count is 100 (so by default, this template generates values between 0 and 99) and must be non-zero.
- The default seed is {{#time:z}} and can be set to any other integer value (used to generate distinct values on the same page).
- The default prime is 67 and should be a prime number above 17 (used to generate distinct values on the same page).
- Examples generating numbers between 0 and 999:
- {{Rand|1000}} = 803
- {{Rand|1000|269|67}} = 803 (same as above)
- {{Rand|1000|269|61}} = 505 (this and others should all be different)
- {{Rand|1000|6}} = 182
- {{Rand|1000|5}} = 115
- {{Rand|1000|4}} = 48
- {{Rand|1000|3}} = 981
- {{Rand|1000|2}} = 914
- {{Rand|1000|1}} = 847
- {{Rand|1000|0}} = 780
- {{Rand|1000|1|17}} = 558 (varying the prime number)
- {{Rand|1000|1|19}} = 447
- {{Rand|1000|1|23}} = 216
- {{Rand|1000|1|29}} = 898
- {{Rand|1000|1|31}} = 774
- {{Rand|1000|1|37}} = 457
- {{Rand|1000|1|41}} = 233
- {{Rand|1000|1|43}} = 120
- {{Rand|1000|1|47}} = 893
- {{Rand|1000|1|51}} = 654
- {{Rand|1000|1|53}} = 538
- {{Rand|1000|1|59}} = 213
- {{Rand|1000|1|61}} = 96
- {{Rand|1000|1|67}} = 780
- {{Rand|1000|1|71}} = 564
- {{Rand|1000|1|73}} = 479
- {{Rand|1000|1|79}} = 110
Notes
- Varying seed generates numbers in a linear sequence on the same page, with equal cyclic steps.
- Varying prime (provided that it is a prime number) generates pseudo-random numbers that have independent random distribution.
- Note that when count is even (such as 100 by default, or 1000 in the examples above), the generated numbers (on the same page) are all odd or all even when you are varying the seed or prime, unless half of the calls use an even seed and the others used an odd seed. However, later invokations will still alternate odd and even numbers on output (this problem only occurs on the same page where multiple random numbers are invoked).
- On the same page, multiple invokations of this template with the same parameters will generate the same output value, so it is possible to create multiple links related to the same article.
