NAME ^

Math::NumSeq::Repdigits -- repdigits 11, 22, 33, etc

SYNOPSIS ^

 use Math::NumSeq::Repdigits;
 my $seq = Math::NumSeq::Repdigits->new (radix => 10);
 my ($i, $value) = $seq->next;

DESCRIPTION ^

The sequence of repdigit numbers,

    0, 1 ... 9, 11, 22, 33, ... 99, 111, 222, 333, ..., 999, etc
    starting i=0

comprising repetitions of a single digit. The default is decimal or a radix parameter can be given.

FUNCTIONS ^

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

$seq = Math::NumSeq::Repdigits->new ()
$seq = Math::NumSeq::Repdigits->new (radix => $r)

Create and return a new sequence object.

Random Access

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

Return the $i'th repdigit.

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

Return true if $value is a repdigit in the given radix.

$i = $seq->value_to_i_ceil($value)
$i = $seq->value_to_i_floor($value)

Return the $i index of $value, rounding up or down if $value is not a repdigit.

$i = $seq->value_to_i_estimate($value)

Return an estimate of the i corresponding to $value.
