RandomTools Flavor: integer

describe a flavor of a random integer

 Calling Sequence integer integer(opt)

Parameters

 opt - equation of the form range = value; specify options for the random integer

Description

 • The flavor integer describes a random integer in a particular range.
 To describe a flavor of a random integer, use either integer or integer(opt) (where opt is as described below) as the argument to RandomTools[Generate] or as part of a structured flavor.
 • By default, the flavor integer describes a random integer in the range $-499999999994..499999999994$, inclusive.
 • You can modify the properties of the random integer by using the integer(opt) form of this flavor. The opt argument can contain one or more of the following equations.
 range = a..b
 This option specifies the range from which the random integer is chosen.
 The endpoints must be of type integer and they describe a random integer in the interval $a..b$, inclusive.
 If the left-hand endpoint of the range is greater than the right-hand endpoint, an exception is raised.
 exclude= {n1,n2,...}
 This option specifies one or more individual integers that should be excluded from the possible return values.
