<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=
inds of data.<br>
<br>
Introducing: the &quot;approximately equal&quot; (or &quot;approx-equal&quo=
t;) operator `~=3D` (to immitate the maths symbol =E2=89=83).<br>
This combines the power of type coercion with approximating equality.<br>
