Since the C++ standard library implementations (ostringstream,ostrstream,to_string) are slow, they are turned off by default. User can re-enable them by definingRUN_CPPITOAmacro. Some results of various configurations are located atitoa-benchmark/result. They can be accessed online, with interactiv...
