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.
