Math::NumSeq::Palindromes -- palindrome numbers like 15351
use Math::NumSeq::Palindromes; my $seq = Math::NumSeq::Palindromes->new; my ($i, $value) = $seq->next;
The palindrome numbers which read the same backwards and forwards.
0 .. 9, 11, 22, ..., 99, 101, 111, 121, ... 191, 202, ...
The default is decimal or the
radix parameter can select another base.
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::Palindromes->new ()
$seq = Math::NumSeq::Palindromes->new (radix => $r)
Create and return a new sequence object.
$value = $seq->ith($i)
$i'th palindrome number.
$bool = $seq->pred($value)
Return true if
$valueis a palindrome, ie. its digits read the same forwards and backwards (in the given
