FWIW, that's not dependent typing, because the type doesn't depend on run-time values. A bool is either true or false, a [0...1] is either 0 or, ..., or 1.

As for which languages allow it. I'm not sure for floats, but Pascal let you do it for ints for sure. https://wiki.freepascal.org/subrange_types
