Random

Random[ ] gives a uniformly distributed pseudorandom Real in the range 0 to 1.

Random[type, range] gives a pseudorandom number of the specified type, lying in the specified range. Possible types are: Integer, Real and Complex. The default range is 0 to 1. You can give the range min, max explicitly; a range specification of max is equivalent to 0, max.

Random[Integer] gives 0 or 1 with probability .

Random[Complex] gives a pseudorandom complex number in the rectangle with corners and .

Random[Complex, zmin, zmax] uses the rectangle defined by zmin and zmax.

Random[Real, range, n] generates a pseudorandom real number with n-digit precision. Both leading and trailing digits may be chosen as 0.

Random gives a different sequence of pseudorandom numbers whenever you run Mathematica. You can start Random with a particular seed using SeedRandom.
