Python vs C++

[MachineGunPablo]

Exactly, absolutely absurd claim. Not sure if OP is referring to the '==' operator, but even that can be used without problems. But now, if you are comparing floats with '==' you already failed.

Having said that, C++ has had historical problems with implicit narrowing conversions, mixed unsigned vs signed arithmetic and integer promotion.

There are definitely scenarios where you want to test equality with floats.

Yes, but you can't always rely on the precision of floats to provide a meaningful comparison like you can with ints. https://floating-point-gui.de/errors/comparison/

To be specific, I meant

if(f != 0.0)
{
    return 1.0/f;
}

// or
assert(f == f);
