NAME

Math::NumSeq::PrimesDigits -- digits of the primes

SYNOPSIS

use Math::NumSeq::PrimesDigits;
my $seq = Math::NumSeq::PrimesDigits->new;
my ($i, $value) = $seq->next;

DESCRIPTION

This is the digits of the primes,

starting i=1 (for prime=2)
2, 3, 5, 7, 1, 1, 1, 3, 1, 7, 1, 9, 2, 3, 2, 9, ...

            \--/  \--/  \--/  \--/  \--/  \--/
             11    13    17    19    23    29

Order

The optional order parameter (a string) can control the order of the primes of each integer,

order => "forward"     the default
order => "reverse"
order => "sorted"

"reverse" rearranges the values to reverse the digits within each prime, so going from least significant digit. For example 13 appears as 3,1.

2, 3, 5, 7, 1, 1, 3, 1, 7, 1, 9, 1, 3, 2, 9, 2, ...

            \--/  \--/  \--/  \--/  \--/  \--/
             11    13    17    19    23    29

"sorted" rearranges the values to sort the digits within each prime into ascending order.

2, ... 2, 9, 1, 3, 3, 7, 1, 4, 3, 4, 4, 7, 3, 5, ...

       \--/  \--/  \--/  \--/  \--/  \--/  \--/
        29    31    37    41    43    47    53

FUNCTIONS

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

$seq = Math::NumSeq::Digit->new ()
$seq = Math::NumSeq::Digit->new (radix => $r, order => $o)

Create and return a new sequence object.

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

Return true if $value occurs in the sequence, which simply means digits 0 to radix-1.
