fixed-width floating-point types such as `std::float64_t`, `std::float32_t`,
`std::float16_t`, and `std::bfloat16_t`.
* We only support the decimal format: we do not support hexadecimal strings.
* For values that are either very large or very small (e.g., `1e9999`), we
represent it using the infinity or negative infinity value and the returned
* For values that are very large positives or negatives (e.g., `1e9999`), we
represent them using a positive or negative infinity and the returned
`ec` is set to `std::errc::result_out_of_range`.
* For values that are very close to zero (e.g., `1e-9999`), we represent them
using a positive or negative zero and the returned `ec` is set to
`std::errc::result_out_of_range`.
We support Visual Studio, macOS, Linux, freeBSD. We support big and little
endian. We support 32-bit and 64-bit systems.
