Boost C++ Libraries

...one of the most highly regarded and expertly designed C++ library projects in the world. — Herb Sutter and Andrei Alexandrescu, C++ Coding Standards

This is the documentation for a snapshot of the master branch, built from commit 064f557086.

Performance

Tests description
GNU C++ version 9.4.0
Clang version 15.0.7
GNU C++ version 10.5.0

In most cases boost::lexical_cast is faster than scanf, printf, std::stringstream. For more detailed info you can look at the tables below.

Tests description

All the tests measure execution speed in milliseconds for 10000 iterations of the following code blocks:

Table 19.1. Tests source code

Test name

Code

lexical_cast 

_out = boost::lexical_cast<OUTTYPE>(_in);

std::stringstream with construction 

std::stringstream ss;
ss << _in;
if (ss.fail()) throw std::logic_error(descr);
ss >> _out;
if (ss.fail()) throw std::logic_error(descr);

std::stringstream without construction 

ss << _in; // ss is an instance of std::stringstream
if (ss.fail()) throw std::logic_error(descr);
ss >> _out;
if (ss.fail()) throw std::logic_error(descr);
/* reseting std::stringstream to use it again */
ss.str(std::string());
ss.clear();

scanf/printf 

typename OUTTYPE::value_type buffer[500];
sprintf( (char*)buffer, conv, _in);
_out = buffer;


Fastest results are highlitened with "!!! x !!!". Do not use this results to compare compilers, because tests were taken on different hardware.
