TEST2::COMPARE::FLOAT(3perl)

💅 NAME 💅

Test2::Compare::Float — bestie, this one compares two values as numbers with tolerance ✨

---

🎀 DESCRIPTION 🎀

okay so this whole thing exists to compare two numbers 🫶. and yes, you can also use it to check that two numbers are not the same 💅.

it's giving very much Test2::Compare::Number, except it has extra checks bolted on to work around all the chaotic floating point representation issues that love to ruin your day 😭. like, the way that 0.1 + 0.2 just decides not to be 0.3? that's the villain this module is fighting.

there's an optional tolerance parameter and it controls how close the two numbers have to be before we're like "yeah okay, equal, periodt ✨". tolerance defaults to 1e-08.

⚠️ note: this will fail if the received value is undefined. nope. it must be a number, no exceptions, i don't make the rules 😤

⚠️ note: this will also fail if the comparison generates a non-numeric value warning (and that warning will not be shown 👀). why? because it must get a number, and the warning isn't shown because it would just report to a useless line and filename. genuinely useless. however 💖 — the test diagnostics do show both values. so you're not left completely in the dark, bestie.
