NAME ^

Math::Random::OO::Uniform - Generates random numbers from the uniform distribution

VERSION ^

version 0.22

SYNOPSIS ^

  use Math::Random::OO::Uniform;
  push @prngs,
      Math::Random::OO::Uniform->new(),     # range [0,1)
      Math::Random::OO::Uniform->new(5),    # range [0,5)
      Math::Random::OO::Uniform->new(-1,1); # range [-1,1)
  $_->seed(42) for @prngs;
  print( $_->next() . "\n" ) for @prngs;

DESCRIPTION ^

This subclass of Math::Random::OO generates random reals from a uniform probability distribution.

METHODS ^

new

 $prng1 = Math::Random::OO::Uniform->new();
 $prng2 = Math::Random::OO::Uniform->new($high);
 $prng3 = Math::Random::OO::Uniform->new($low,$high);

new takes up to two optional parameters and returns a new Math::Random::OO::Uniform object. With no parameters, the object generates random numbers in the range of zero (inclusive) to one (exclusive). With a single parameter, the object generates random numbers from zero (inclusive) to the value of the parameter (exclusive). Note, the object does this with multiplication, so if the parameter is negative, the function will return negative numbers. This is a feature or bug, depending on your point of view. With two parameters, the object generates random numbers from the first parameter (inclusive) to the second parameter (exclusive). (Actually, as long as you have two parameters, new will put them in the right order).

seed

 $rv = $prng->seed( @seeds );

This method seeds the random number generator. At the moment, only the first seed value matters. It should be a positive integer.

next

 $rnd = $prng->next();

This method returns the next random number from the random number generator. It does not take any parameters.
