Three of the seven FP calls are in test code with one of them used to formatĪctcd19/main/g/gnss-sdr/gnss-sdr_0.0.10-4/src/tests/unit-tests/signal-processing-blocks/tracking/gps_l1_ca_dll_pll_tracking_:916 The two remaining cases are a generic wrapper around std :: to_string and an overload for a user-defined type. Note that some of these 7 results contain calls with integral and FP arguments Integral arguments and only 7 contain calls with floating-point arguments. We further analyzed a random sample of 100 std :: to_string invocations listed in Appendix A. For comparison, thereĪre ~20 thousand uses of std :: stringstream and ~390 thousand calls to sprintf. 876 million lines of codeĬontained only ~11 thousand calls to this function. In order to estimate the practical impact on existing code we looked at results for std :: to_string. In cases where the C locale is explicitly set the decimal point will no longer In most cases it will result in a more precise and/or shorter output. This change will affect the output of std :: to_string with floating-pointĪrguments. In addition to fixing the broken behavior for floating point, this proposalĮnables an easy and natural extension of std :: to_string to other types via std :: format (not proposed in this paper). Unlocalized and use the shortest decimal representation. Unlocalized and changing the format of floating-point overloads to also be Redefine std :: to_string in terms of std :: format which in turn uses std :: to_chars making more explicit the fact that integral overloads are ( ) which proposed deprecating floating-point overloads of std :: to_string but no paper came out of that.
However, they were brought up as early as 2015 in a mailing list discussion Unfortunately issues with floating-point overloads of std :: to_string have notīeen discussed in the paper that proposed this facility (, ). In fact almost half of floating-point numbers are formatted as zero and there isĪ precision loss or garbage digit output in many other cases. For example: std :: cout << std :: to_string ( -1e-7 ) And finally we have 6 meaningless zeros after aįormatting of small floating-point numbers is even less useful. Here only the first 17 digits are meaningful, the next 292 are so-called

Fortunately for integral and unfortunately forįloating-point overloads they are all defined in terms of sprintf inconsistently with C++ formatted output functions ( ).
