Primitive types are really annoying.

If they were about what user needs not about underlying hardware they'd be fine.

I dont care about int, long, float or double.

I care about number to represent whole amount, or fractional amount or approximate amount with operations that work accordingly lile approximate comparison of approximate numbers. Approximations for when I care about approximation error and for when I don't. Number that are limited to the ranges I care about not some arbitrary MAX_INT. Numbers that have units so that I won't accidently assigned a length to a variable that should hold mass.

So yeah, as they are primitive types do introduce unnecessary complexity and none useful complexity unless you want to work close to the metal.
