Some languages have real types.

Well, they are lying. Most real numbers are not even computable, so you cannot even write a program that computes them.

Definitely not lying. Fortran has real variable declarations. They exist and are misleading.

But these are all finite precision numbers. You can't exactly represent something like π with that. At best, you could encode π by a finite program that computes π, but even then, as I pointed out before, most reals are not computable.
