The C language established the +precedent that these small values are out of range. In such cases, it is +customary to parse small values to zero and large values to infinity. That is +the behaviour of the C language (e.g., `stdtod`). That is the behaviour followed +by the fast_float library. + +Specifically, we follow Jonathan Wakely's interpretation of the standard: + +> In any case, the resulting value is one of at most two floating-point values +> closest to the value of the string matching the pattern. + +It is also the approach taken by the [Microsoft C++ +library](https://github.com/microsoft/STL/blob/62205ab155d093e71dd9588a78f02c5396c3c14b/tests/std/tests/P0067R5_charconv/test.cpp#L943-L946). + +Hence, we have the following examples: + +```cpp + double result = -1; + std::string str = "3e-1000"; + auto r = fast_float::from_chars(str.data(), str.data() + str.size(), result); + // r.ec == std::errc::result_out_of_range + // r.ptr == str.data() + 7 + // result == 0 +``` + +```cpp + double result = -1; + std::string str = "3e1000"; + auto r = fast_float::from_chars(str.data(), str.data() + str.size(), result); + // r.ec == std::errc::result_out_of_range + // r.ptr == str.data() + 6 + // result == std::numeric_limits::infinity() +``` + +Users who wish for the value to be left unmodified given +`std::errc::result_out_of_range` may do so by adding two lines of code: + +```cpp + double old_result = result; // make copy + auto r = fast_float::from_chars(start, end, result); + if (r.ec == std::errc::result_out_of_range) { result = old_result; } ``` ## C++20: compile-time evaluation (constexpr) -In C++20, you may use `fast_float::from_chars` to parse strings -at compile-time, as in the following example: +In C++20, you may use `fast_float::from_chars` to parse strings at compile-time, +as in the following example: ```C++ // consteval forces compile-time evaluation of the function in C++20. consteval double parse(std::string_view input) { double result; - auto answer = fast_float::from_chars(input.data(), input.data()+input.size(), result); - if(answer.ec != std::errc()) { return -1.0; } + auto answer = fast_float::from_chars(input.data(), input.data() + input.size(), result); + if (answer.ec != std::errc()) { return -1.0; } return result; } @@ -167,108 +240,107 @@ constexpr double constexptest() { ## C++23: Fixed width floating-point types -The library also supports fixed-width floating-point types such as `std::float32_t` and `std::float64_t`.
