Takes an lvalue reference, and returns the same reference.
This allows non-default constructible types to be converted without
specializing adl_serializer.
This overload does not require CopyConstructible either.
Implements #1227
"Concepts" have been renamed to "named requirements".
This is because P0898R3 Standard Library Concepts has been merged into
C++20.
Cppreference have moved their links accordingly.
The README says:
> "The library itself contains of a single header file ..."
I guess "consists of a" is the wording that was intended here. Alternatively, "contains a" might also be what was intended. Either way, I think both versions work equally well and thus choose the one that I believe was intended.
I contributed a package to the Spack package manager.
Spack is a flexible package manager that supports multiple versions,
configurations, platforms, and compilers. It is popular in
high-performance computing.
Beside the fix discussed in #961, we also had to re-adjust a test case. It seems that it was failing before, and I "fixed" it to work with the broken implementation...
- updated documentation wrt. new repository layout
- temporarily switched off Homebrew --HEAD building (can only be switched on after release)
- set copyright date to 2018
This is an attempt to fix#360. The algorithm produces
decimal representations which are guaranteed to roundtrip
and in ~99.8% actually produces the shortest possible
representation. So this is a nice compromise between using
a precision of digits10 and max_digits10.
Note 1:
The implementation only works for IEEE single/double precision
numbers. So the old implementation is kept for compatibility
with non-IEEE implementations and 'long double'.
Note 2:
If number_float_t is 'float', not all serialized numbers can
be recovered using strtod (strtof works, though). (There is
exactly one such number and the result is off by 1 ulp.)
This can be avoided by changing the implementation (the fix
is trivial), but then the resulting decimal numbers are not
exactly short.
