# 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 1 is divisible only by itself. Then i=2 is divisible by 1 and 2. Or for example i=6 is divisible by 4 numbers 1,2,3,6.

# FUNCTIONS

See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.

`\$seq = Math::NumSeq::DivisorCount->new ()`

Create and return a new sequence object.

## Random Access

`\$value = \$seq->ith(\$i)`

Return the number of prime factors in `\$i`.

This calculation requires factorizing `\$i` and in the current code a hard limit of 2**32 is placed on `\$i`, in the interests of not going into a near-infinite loop.

`\$bool = \$seq->pred(\$value)`

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