You can select Repeat and/or Random from Now Playing in the onscreen display. Repeat plays the Now Playing list repeatedly; when it reaches the end it automatically starts over again at the beginning. Random plays all the songs in the Now Playing list in random order rather than sequentially. If both Random and Repeat are selected, the music will play continuously in random order. If neither is selected, the Now Playing list of songs will play sequentially and then stop at the end. See similar questions...

How do I get random numbers?

Java Programmer's FAQ
The notation "[0,1)" is common math notation for "zero to .9999999 etc" The Sun documents say this returns 0.0 to 1.0, but inspection of the source shows they are wrong. However, due to the inherent inaccuracies of floating point arithmetic, multiplying N by 0.999999 etc can result in an answer of N, not N * .999999 . So watch out when N is big.

How do I generate random numbers?

The BYOND FAQ
rand() is used to generate a random number between its first value and its second value. Eg. var/num = rand(1,10) will set num to a random number between one and ten. prob() is used to check a probability out of 100; it will return 1 if the check is true, or 0 if the check is false. For example, prob(50) will have a 50% chance of returning 1 and a 50% chance of returning 0. prob(25) will have but a 25% chance of returning 1 and a 75% chance of returning 0.

MaizeGDB Docs: Maize Gene Discovery Project: ESTs: Assembly:...
Time, money, etc.; there are real limitations. For the first half of the EST project we are reverse sequencing about 10-15% of the 96 well plates. We choose the plates with the highest yield of unique sequences in the forward direction. From the forward and reverse sequence we gain valuable insight into the average insert length for a library, and we maximize the chances of forming long contigs during the final assembly.
