I don't need to be better than him.
This is not a complex type of math.
This is something that every fiftgrader studies.

There is = and there is ~= .

For every practical reason it doesn't matter. For computers it doesn't matter. Nor does it matter for engenders.

But the fact that it doesn't matter doesn't mean that it is the same. (There is no equality between these claims, just like there is no equality between 1 and 'not 1'.)

Btw - I am a software developer. I also work a lot with numbers.
