I know it's a cooked idea, but I half wish I could operator overload ==, >, < etc for floats to automatically include an epsilon...

or maybe a new operator like `a ~= b`
in languages like odin or jai you could even store the value of epsilon in the context

I love that syntax, my brain already associates ~ with “approximately equal”

I mean, I get why == should have an epsilon.

But can anyone tell me why < or > need an epsilon? I don't get it.

Just me wanting to avoid problems with small accumulated error without having to check the equals before every comparison - in this case I’m probably better off using a fixed point representation 🙂

I want stuff like interval arithmetic or some better floats. But the hardware does not accelerate them as well.

You know there are proposals like posits and stuff, but I haven't used them and likely won't so I don't have a valuable opinion on replacing clasic IEEE754.

Can confirm, it's cooked :D
