\subsection random-description Description
|
|
|
|
|
|
|
|
The \c random command is used to generate a random number in the
|
|
|
|
interval 0<=N<32767. If an argument is given, it is used to seed the
|
|
|
|
random number generator. This can be useful for debugging purposes,
|
|
|
|
where it can be desirable to get the same random number sequence
|
|
|
|
multiple times. If the random number generator is called without first
|
|
|
|
seeding it, the current time will be used as the seed.

|
|
|
|
<pre>
|
|
|
|
for i in (seq (random) -1 1)
|
