Test::...::Fuzzy(3pm)

💖 Test::...::Fuzzy — the manual page, but make it cute ✨

okay bestie, you're looking at the docs for Test::Deep::Fuzzy, a lil module in the User Contributed Perl Documentation pile. it does exactly one thing and it does it adorably: fuzzy number comparison with Test::Deep. no cap 💅

---

✨ NAME ✨

Test::Deep::Fuzzy — fuzzy number comparison with Test::Deep 🦋

like. that's the whole personality. floats are messy, this module is not.

---

🌸 SYNOPSIS 🌸

here's the vibe, copy-paste ready:

use Test::Deep;
use Test::Deep::Fuzzy;

my $range = 0.001;

cmp_deeply({
    number => 0.0078125,
}, {
    number => is_fuzzy_num(0.008, $range),
}, 'number is collect');

see how 0.0078125 and 0.008 are not the same number but the test still passes? yeah. that's the whole serve. slay ✨

---

🎀 DESCRIPTION 🎀

Test::Deep::Fuzzy provides fuzzy number comparison with Test::Deep. that's it, that's the description, and honestly? iconic. sometimes a girl just wants her floats to be close enough and not have a whole meltdown about it 😭

---

💅 FUNCTIONS 💅

🫶 is_fuzzy_num EXPECTED, RANGE

this is the one function, the main character, the moment 👑

• it rounds the values before comparing the values. so instead of a brutal exact-equality vibe check, everything gets rounded first and then compared. much more forgiving, much more chill 🌈
• the RANGE is what gets handed to Math::Round::nearest() to compare the values. so like, RANGE is your tolerance zone, your little bubble of "close enough bestie" 💖

---

🔥 SEE ALSO 🔥

go be nosy, i support it:

• Math::Round
• Test::Deep
• Test::Number::Delta
