12e5b6d6dSopenharmony_cihttps://github.com/google/double-conversion 22e5b6d6dSopenharmony_ci 32e5b6d6dSopenharmony_ciThis project (double-conversion) provides binary-decimal and decimal-binary 42e5b6d6dSopenharmony_ciroutines for IEEE doubles. 52e5b6d6dSopenharmony_ci 62e5b6d6dSopenharmony_ciThe library consists of efficient conversion routines that have been extracted 72e5b6d6dSopenharmony_cifrom the V8 JavaScript engine. The code has been refactored and improved so that 82e5b6d6dSopenharmony_ciit can be used more easily in other projects. 92e5b6d6dSopenharmony_ci 102e5b6d6dSopenharmony_ciThere is extensive documentation in `double-conversion/string-to-double.h` and 112e5b6d6dSopenharmony_ci`double-conversion/double-to-string.h`. Other examples can be found in 122e5b6d6dSopenharmony_ci`test/cctest/test-conversions.cc`. 132e5b6d6dSopenharmony_ci 142e5b6d6dSopenharmony_ci 152e5b6d6dSopenharmony_ciBuilding 162e5b6d6dSopenharmony_ci======== 172e5b6d6dSopenharmony_ci 182e5b6d6dSopenharmony_ciThis library can be built with [scons][0] or [cmake][1]. 192e5b6d6dSopenharmony_ciThe checked-in Makefile simply forwards to scons, and provides a 202e5b6d6dSopenharmony_cishortcut to run all tests: 212e5b6d6dSopenharmony_ci 222e5b6d6dSopenharmony_ci make 232e5b6d6dSopenharmony_ci make test 242e5b6d6dSopenharmony_ci 252e5b6d6dSopenharmony_ciScons 262e5b6d6dSopenharmony_ci----- 272e5b6d6dSopenharmony_ci 282e5b6d6dSopenharmony_ciThe easiest way to install this library is to use `scons`. It builds 292e5b6d6dSopenharmony_cithe static and shared library, and is set up to install those at the 302e5b6d6dSopenharmony_cicorrect locations: 312e5b6d6dSopenharmony_ci 322e5b6d6dSopenharmony_ci scons install 332e5b6d6dSopenharmony_ci 342e5b6d6dSopenharmony_ciUse the `DESTDIR` option to change the target directory: 352e5b6d6dSopenharmony_ci 362e5b6d6dSopenharmony_ci scons DESTDIR=alternative_directory install 372e5b6d6dSopenharmony_ci 382e5b6d6dSopenharmony_ciCmake 392e5b6d6dSopenharmony_ci----- 402e5b6d6dSopenharmony_ci 412e5b6d6dSopenharmony_ciTo use cmake run `cmake .` in the root directory. This overwrites the 422e5b6d6dSopenharmony_ciexisting Makefile. 432e5b6d6dSopenharmony_ci 442e5b6d6dSopenharmony_ciUse `-DBUILD_SHARED_LIBS=ON` to enable the compilation of shared libraries. 452e5b6d6dSopenharmony_ciNote that this disables static libraries. There is currently no way to 462e5b6d6dSopenharmony_cibuild both libraries at the same time with cmake. 472e5b6d6dSopenharmony_ci 482e5b6d6dSopenharmony_ciUse `-DBUILD_TESTING=ON` to build the test executable. 492e5b6d6dSopenharmony_ci 502e5b6d6dSopenharmony_ci cmake . -DBUILD_TESTING=ON 512e5b6d6dSopenharmony_ci make 522e5b6d6dSopenharmony_ci test/cctest/cctest 532e5b6d6dSopenharmony_ci 542e5b6d6dSopenharmony_ci[0]: http://www.scons.org/ 552e5b6d6dSopenharmony_ci[1]: https://cmake.org/ 56
