**Affected subclause:** [[string.conversions]](string.conversions)  


**Change:** Output of floating-point overloads of to_string and to_wstring[.](#1.sentence-1)

  


**Rationale:** Prevent loss of information and improve consistency with other formatting
facilities[.](#1.sentence-2)

  


**Effect on original feature:** to_string and to_wstring function calls that take
floating-point arguments may produce a different output[.](#1.sentence-3)

[*Example [1](#example-1)*: auto s = std::to_string(1e-7); // "1e-07"// previously "0.000000" with '.' possibly// changed according to the global C locale — *end example*]
