NAME

Math::NumSeq::DigitLength -- length in digits

SYNOPSIS

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

DESCRIPTION

The length in digits of integers 0 upwards, so for example ternary 1,1,1,2,2,...,2,3,etc. Zero is reckoned as length 1, a single digit 0.

FUNCTIONS

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

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

Create and return a new sequence object.

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

Return length in digits of $i.

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

Return true if $value >= 1, all lengths being 1 or more.
