u “RandSeed” Command

•You can specify an integer from 0 to 9 for the argument of this command. 0 specifies non- sequential random number generation. An integer from 1 to 9 uses the specified value as a seed for specification of sequential random numbers. The initial default argument for this command is 0.

•The numbers generated by the ClassPad immediately after you specify sequential random number generation always follow the same random pattern.

Tip

•Random values generated by these commands are pseudo random values.

•The arguments a and b of “rand(a,b)” and “randList(n,a,b)” must be integers, subject to the following conditions.

a < b

a, b< 1E10 b – a < 1E10
