Floating-point numbers usually resolve to `double` during compilation.
This is a good default case and use-cases with the narrower `float` type are less frequent than the unsigned example above.

~~~~exercism/advanced
The [C++23 standard][cpp23-literals] introduces more fine grained control with literals like `f128` or `F16`.
Some compilers allow their own literals.
GCC permits the usage of `d` as a literal, but this is not forseen in the standard and can hinder cross-platform compatibility.
