Class Environment.Random

Class used to generate random numbers. This class should always be used when random numbers are needed. There is a seed property that the user can control in the Experior GUI. The seed value is used by this class. The seed property in the GUI will not (automatically) affect other random number generators (if used).

Syntax

public class Random

Properties

Generator

The random generator used by the class.

Declaration

public static StandardGenerator Generator { get; }

Property Value

Type	Description
StandardGenerator

Seed

The seed used to generate the pseudo random numbers.

Declaration

public static int Seed { get; set; }

Property Value

Type	Description
System.Int32

Methods

Next()

Returns a nonnegative random number.

Declaration

public static int Next()

Returns

Type	Description
System.Int32	A 32-bit signed integer greater than or equal to zero and less than System.Int32.MaxValue.

Next(Int32)

Returns a nonnegative random number less than the specified maximum.

Declaration

public static int Next(int max)

Parameters

Type	Name	Description
System.Int32	max	The exclusive upper bound of the random number to be generated. max must be greater than or equal to 0.

Returns

Type	Description
System.Int32	A 32-bit signed integer greater than or equal to 0, and less than max; that is, the range of return values includes 0 but not max.

Next(Int32, Int32)

Returns a random number within a specified range.

Declaration

public static int Next(int min, int max)

Parameters

Type	Name	Description
System.Int32	min	The inclusive lower bound of the random number to be generated.
System.Int32	max	The exclusive upper bound of the random number to be generated. max must be greater than or equal to min.

Returns

Type	Description
System.Int32	A 32-bit signed integer greater than or equal to min, and less than max; that is, the range of return values includes min but not max. If min equals max, min is returned.

NextDouble()

Returns a nonnegative floating point random number less than 1.0.

Declaration

public static double NextDouble()

Returns

Type	Description
System.Double	A double-precision floating point number greater than or equal to 0.0, and less than 1.0; that is, the range of return values includes 0.0 but not 1.0.

NextDouble(Double)

Returns a nonnegative floating point random number less than the specified maximum.

Declaration

public static double NextDouble(double max)

Parameters

Type	Name	Description
System.Double	max	The exclusive upper bound of the random number to be generated. max must be greater than or equal to zero.

Returns

Type	Description
System.Double	A double-precision floating point number greater than or equal to zero, and less than max; that is, the range of return values includes zero but not max.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException

NextDouble(Double, Double)

Returns a floating point random number within the specified range.

Declaration

public static double NextDouble(double min, double max)

Parameters

Type	Name	Description
System.Double	min	The inclusive lower bound of the random number to be generated. The range between min and max must be less than or equal to System.Double.MaxValue
System.Double	max	The exclusive upper bound of the random number to be generated. max must be greater than or equal to min. The range between min and max must be less than or equal to System.Double.MaxValue.

Returns

Type	Description
System.Double	A double-precision floating point number greater than or equal to min, and less than max; that is, the range of return values includes min but not max. If min equals max, min is returned.

Exceptions

Type	Condition
System.ArgumentOutOfRangeException
System.ArgumentException

Reset()

Resets the StandardGenerator, so that it produces the same pseudo-random number sequence again.

Declaration

public static void Reset()
