C# Class RandomOps.RanSystem

Wrapper for the .NET built-in PRNG. Not thread-safe by default.

Since the .NET implementation may change we cannot override and make a more efficient implementation of Byte() that would use bit-manipulation, because it would assume things about the implementation that might change.

Public Methods

Method	Description
Bool ( ) : bool	Draw a random boolean with equal probability of drawing true or false.
Byte ( ) : byte	Draw a random and uniform byte.
Bytes ( int length ) : byte[]	Draw an array of random and uniform bytes.
Index ( int n ) : int	Draw a random index from the range {0, .., n-1}
RanSystem ( )	Constructs the PRNG-object and seeds the PRNG with the current time of day. This is what you will mostly want to use.
RanSystem ( int seed )	Constructs the PRNG-object using the designated seed. This is useful if you want to repeat experiments with the same sequence of pseudo-random numbers.
Uniform ( ) : double	Draw a uniform random number in the exclusive range (0,1)

Byte() public final method

Draw a random and uniform byte.

public final Byte ( ) : byte
return	byte

Bytes() public final method

Draw an array of random and uniform bytes.

public final Bytes ( int length ) : byte[]
length	int	The array length requested.

RanSystem() public method

Constructs the PRNG-object and seeds the PRNG with the current time of day. This is what you will mostly want to use.

public RanSystem ( )

RanSystem() public method

Constructs the PRNG-object using the designated seed. This is useful if you want to repeat experiments with the same sequence of pseudo-random numbers.
