randomAny data or information that has no order. For example, 5,8,2,9, and 0 are single-digit numbers that are in random order. Data that is random can be sorted by date, name, time, age, etc.

Data can be randomly selected or random numbers can be generated using a random seed. Computer games, web pages, programs, and encryption are just a few examples of what needs random values to operate. For example, Computer Hope has a random dictionary definition script that randomly selects and opens a random dictionary page for Computer Hope users.

Random number in programming

In programming languages, there is often a command, function, or random number generator (rng) that allows the developer to generate a random number. For example, in Perl the programmer could use rand to generate a random number. Below is an example of generating a random whole number in Perl.

my $random = int(rand(10));
print "Random number between 0 and 10: $random\n";

In the above example, the $random variable is assigned a random whole number between zero and ten and then prints that random number.

Random number in Excel
