Well, you will find that assignment of an expression of derived type to a
variable of the same type was already available in Fortran 95 (for example
Metcalf, 1999, Fortran 90/95 explained, section 3.9). But

Nope, ceilf comes from C, which has no overloading.
C++ doesn't need separate names for ceil, ceilf and ceill, so you just have
std::ceil.
The fact std::ceilf exists at all is just for consistency with

Thanks Jonathan, but I disagree. The point is that the caller might be wrong in
any number of assumptions. The library designers were in agreement, hence why
there is an explicit ceilf function.
