Math::NumSeq::DigitLength -- length in digits
use Math::NumSeq::DigitLength; my $seq = Math::NumSeq::DigitLength->new (radix => 10); my ($i, $value) = $seq->next;
The length in digits of integers 0 upwards,
The default is decimal digits, or the optional
radix can give another base. For example ternary
Zero is reckoned as a single digit 0 which is length 1.
See "FUNCTIONS" in Math::NumSeq for behaviour common to all sequence classes.
$seq = Math::NumSeq::DigitLength->new (radix => $r)
Create and return a new sequence object.
$value = $seq->ith($i)
Return length in digits of
$bool = $seq->pred($value)
Return true if
$valueoccurs as a digit length. This means simply
$value >= 1since lengths are 1 or more.
