NAME
Math::NumSeq::DivisorCount -- how many divisors
SYNOPSIS
use Math::NumSeq::DivisorCount;
my $seq = Math::NumSeq::DivisorCount->new;
my ($i, $value) = $seq->next;
DESCRIPTION
The number of divisors of i, being 1,2,2,3,2,4,2, etc.
The sequence starts from i=1 and that 1 is divisible only by itself. Then i=2 is divisible by 1 and 2, then for instance 6 is divisible by 4 numbers 1,2,3,6.
FUNCTIONS
$seq = Math::NumSeq::DivisorCount->new ()
$seq = Math::NumSeq::DivisorCount->new (divisors_type => 'propn1')
-
Create and return a new sequence object.
$value = $seq->ith($i)
-
Return the number of prime factors in
$i
. $bool = $seq->pred($value)
-
Return true if
$value
occurs as a divisor count, which means simply$value >= 2
.
