compiler error "error: call to deleted function 'from_chars'" for floating point numbers

[FMorkel]

Hi,

std::from_chars seems to be (still) unsupported for floating point numbers (_LIBCPP_VERSION=190100).
Or am I missing something?

Best regards,
Fred

It is currently unimplemented in libc++:

There is a PoC PR upstream, though there is no telling when it will be ready and merged:
