Math::NumSeq::Even(3)

💖 Math::NumSeq::Even — the manual, but make it cute ✨

okay bestie, so you're looking at Math::NumSeq::Even, which lives in the Math::NumSeq family of Perl modules, and it is literally just the even integers. That's it. That's the whole vibe. She's simple, she's iconic, she understood the assignment. 👑

---

🌸 NAME 🌸

Math::NumSeq::Even — even integers 💅

---

✨ SYNOPSIS ✨

here's the whole thing in action, no notes:

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

like. she's thriving. 🦋

---

🎀 DESCRIPTION 🎀

it's the even integers, bestie:

0, 2, 4, 6, 8, 10, ...
starting i=0

that's the sequence. zero, two, four, six, eight, ten, and she keeps going forever because she has main character energy and does not stop. 🌈

💖 FUNCTIONS 💖

for the stuff that's shared across all the sequence classes, go peek at "FUNCTIONS" in Math::NumSeq — that's the group chat everyone's in. 🫶

• $seq = Math::NumSeq::Even->new () — makes a brand new sequence object and hands it to you. fresh out of the box, no cap.

🧚 Iterating

• $seq->seek_to_i($i) — slides the current position of the sequence over to $i. the very next time you call next(), it's gonna hand you back $i plus the matching value. so cute. ✨
• $seq->seek_to_value($value) — moves the current i around so that next() gives you $value on the next call. oh and heads up — if $value is an even integer, you get the next higher even instead. lowkey important, don't forget it. 🙈

💜 Random Access

• $value = $seq->ith($i) — returns 2*$i. that's it. math is mathing. 🔥
• $bool = $seq->pred($value) — returns true if $value is even. vibe check passed ✅
• $i = $seq->value_to_i_ceil($value)
• $i = $seq->value_to_i_floor($value) — returns value/2, rounded up or down to the next integer. pick your fighter. 💅
• $i = $seq->value_to_i_estimate($value) — returns an estimate of the i that corresponds to $value. it's giving approximation, it's giving ballpark, and honestly? we respect it. 🌸
