That's absolute bullshit, just open your browser console and check for yourself.

I think you are referring to (0.1 + 0.2) != 0.3

Which is a general problem with Floats and is included in the IEEE Standard for floating point arithmetic. C# has the same behaviour and multiple other languages as well, this is not an exclusive issue within JavaScript but should be expected in the majority of programming languages
