Hi Niels,

When I was reading it, I felt a bit unsure, but numbers related, it was
making sense.
When you got to strings with `"This is a tpyo" ~=3D "This is a typo"`, I al=
so
remembered today it's 1st of April, so there's that...

I had an epiphany. I realized what we truly need to revolutionize PHP: a ne=

<br>
Hear me out.<br>
We live in an imperfect world, and we often approximate data, but neither `=
=3D=3D` nor `=3D=3D=3D` are ideal comparison operators to deal with these k=

Introducing: the &quot;approximately equal&quot; (or &quot;approx-equal&quo=

This combines the power of type coercion with approximating equality.<br>
Who cares if things are actually equal, close enough amirite?<br><br></bloc=
