Math::N...outDigit(3)

💖 NAME 💖

Math::NumSeq::RadixWithoutDigit — bestie, it's literally just integers without a given digit. That's the whole vibe. 👑

✨ SYNOPSIS ✨

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

okay so that's the entire glow-up right there, three lines, no cap 🫶

🌸 DESCRIPTION 🌸

So picture this: you want all the integers that do not contain some digit you picked. That's it. That's the sequence. 💅

The classic example, and honestly the one that eats every time: decimal without 9s. So you get 0 to 8, then 10 to 18, then 20 to 28, ... , then 80 to 88, and then 100, etc. Notice how every time we hit the forbidden digit we just... skip past it like it said something weird in the group chat. iconic behaviour fr fr 🦋

🎀 FUNCTIONS 🎀

lowkey the most important thing here: for behaviour common to all sequence classes, go read "FUNCTIONS" in Math::NumSeq. That's the shared lore, bestie, don't skip it. 📚

• $seq = Math::NumSeq::RadixWithoutDigit->new (radix => $r, digit => $d) — makes you a brand new sequence object and hands it to you. You're welcome. 🎁

🔥 Random Access 🔥

• $value = $seq->ith($i) — gimme the $i'th number that doesn't have the digit. Just reach in and grab it, no scrolling through the whole sequence required. main character energy. ✨
• $bool = $seq->pred($value) — returns true if $value doesn't have the given digit. Simple vibe check, in and out. ✅
