Hi everybody,

I'm having that when compiling a project with unittests enabled:

```
/Users/pinver/dlang/dmd-2.103.0/osx/bin/../../src/phobos/std/math/exponential.d(3791,36): Error: number `0x0.8p-126f` is not representable as a `float`

```

I've searched a little, but I don't know if it's a known bug or regression.

If you are on MacOS this is because of a change in the macos libc string to float functions, it's been fixed in DMD master
