Random

Usage

• 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}.

Notes

• Random[Integer] gives 0 or 1 with probability

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

and

• Random[Complex, {

}] uses the rectangle defined by

and

• 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.

• See Section 1.1.3 and Section 3.2.4.

• Implementation notes: see Section A.9.4.
