Math::N...epdigits(3)

💖 Math::NumSeq::Repdigits(3) — the manual, but make it cute 💖

okay bestie, so this is the Math::NumSeq::Repdigits(3) page — it's part of the User Contributed Perl Documentation and it's genuinely one of the most satisfying little sequence modules out there. repdigits?? 11, 22, 33?? it's giving aesthetic. let's get into it ✨

🌸 NAME 🌸

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

like. the numbers that are just one digit repeated. no cap, that's the whole vibe.

---

🎀 SYNOPSIS 🎀

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

yes bestie that's it. three lines. load it, build it, start pulling values out one at a time. iconic.

---

✨ DESCRIPTION ✨

so the sequence is literally the repdigit numbers, and they go like this:

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

each one is a repetition of a single digit — one digit, over and over, no switching up. the default is decimal, but you can hand it a "radix" parameter if you want to do this whole thing in some other base. your call, main character 💅

---

🦋 FUNCTIONS 🦋

heads up: for the behaviour that's common to all the sequence classes, go read "FUNCTIONS" in Math::NumSeq. that's the shared lore. iykyk.

• $seq = Math::NumSeq::Repdigits->new ()
• $seq = Math::NumSeq::Repdigits->new (radix => $r) — make a brand new sequence object and hand it back to you. pass radix if you want a specific base instead of the default.

---

🍓 Random Access

• $value = $seq->ith($i) — gimme the $i'th repdigit, thank you very much.
• $bool = $seq->pred($value) — returns true if $value is a repdigit in the given "radix". true/false, yes/no, slay/not-slay.
• $i = $seq->value_to_i_ceil($value)
• $i = $seq->value_to_i_floor($value) — these two give you the $i index of $value, rounding up or down if $value isn't actually a repdigit. (so rude of it not to be, but okay.)
• $i = $seq->value_to_i_estimate($value) — returns an estimate of the i that corresponds to $value. estimate!! not a promise!! 💀
