💖 Math::NumSeq::DigitLength 💖

okay bestie, so this page is Math::NumSeq::DigitLength(3), and it's from the User Contributed Perl Documentation collection (iykyk — the community said "we got this one" 🫶). Let's get into it.

✨ NAME ✨

Math::NumSeq::DigitLength — literally just "how many digits does this number have" 💅

🌸 SYNOPSIS 🌸

no cap, this is the whole vibe:

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

🦋 DESCRIPTION 🦋

okay so it hands you the length in digits of the integers going 0 upwards, and it's giving:

1,1,1,1,1,1,1,1,1,1,2,2,2,2,2,...

the default is decimal digits, but you can pass the optional "radix" if you want a whole other base — main character energy. for example, ternary goes:

1,1,1,2,2,...,2,3,...

and zero? bestie, zero is reckoned as a single digit 0, which is length 1. that's it, that's the rule, periodt.

🎀 FUNCTIONS 🎀

peep "FUNCTIONS" in Math::NumSeq for the behaviour common to all sequence classes — the shared lore, if you will 📖✨

  • $seq = Math::NumSeq::DigitLength->new (radix => $r) — create and return a new sequence object. slay.

🔥 Random Access 🔥

  • $value = $seq->ith($i) — return the length in digits of $i. that's the whole gig 💅
  • $bool = $seq->pred($value) — return true if $value occurs as a digit length. this means simply "$value >= 1" since lengths are 1 or more. lowkey the easiest predicate ever.

and that's the whole page, angel 💖 this little legend dropped as perl v5.42.0, dated 2025-07-25, and yes it's still answering to Math::NumSeq::DigitLength(3). go count some digits, you're doing amazing 🎀✨
