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,
1, 2, 2, 3, 2, 4, 2, 4, 3, 4, 2, 6, 2, 4, 4, 5, 2, 6, 2, ...
starting i=1
i=1 is divisible only by 1 so value=1. Then i=2 is divisible by 1 and 2 so value=2. Or for example i=6 is divisible by 4 numbers 1,2,3,6 so value=4.
FUNCTIONS
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
Random Access
$value = $seq>ith($i)

Return the number of prime factors in
$i
.This calculation requires factorizing
$i
and in the current code after small factors a hard limit of 2**32 is enforced in the interests of not going into a nearinfinite loop. $bool = $seq>pred($value)

Return true if
$value
occurs as a divisor count, which simply means$value >= 1
.
