(WARNING: ABOUT THIS FORK)

This fork was for getting the library to work under Visual Studio 6 primarily, but likely to improve compatibility with compilers in general. The changes here are likely to damage the accuracy of the official implementation. If you wish to deduce how this might, or might not, affect you, note the following for pertaining changes:

• File "double-conversion/string-to-double.cc": Search for ::std::tolower(ch, ::std::locale(""));
• File "double-conversion/string-to-double.cc": The functions StringToDoubleConverter::StringTo() were disabled. Examine
• File "double-conversion/strtod.cc": The private function convertUnsignedInt64ToDouble(unsigned __int64) introduced to be used instead of static_cast(unsigned __int64 t). This might slightly affect performance on newer compilers. On Visual Studio 6, in particular, this might give incorrect results.

Finally, note that tests were not updated to reflect the changes.

https://github.com/google/double-conversion

This project (double-conversion) provides binary-decimal and decimal-binary routines for IEEE doubles.

The library consists of efficient conversion routines that have been extracted from the V8 JavaScript engine. The code has been refactored and improved so that it can be used more easily in other projects.

There is extensive documentation in double-conversion/string-to-double.h and double-conversion/double-to-string.h. Other examples can be found in test/cctest/test-conversions.cc.

Building

This library can be built with scons or cmake. The checked-in Makefile simply forwards to scons, and provides a shortcut to run all tests:

make
make test

Scons

The easiest way to install this library is to use scons. It builds the static and shared library, and is set up to install those at the correct locations:

scons install

Use the DESTDIR option to change the target directory:

scons DESTDIR=alternative_directory install

Cmake

To use cmake run cmake . in the root directory. This overwrites the existing Makefile.

Use -DBUILD_SHARED_LIBS=ON to enable the compilation of shared libraries. Note that this disables static libraries. There is currently no way to build both libraries at the same time with cmake.

Use -DBUILD_TESTING=ON to build the test executable.

cmake . -DBUILD_TESTING=ON
make
test/cctest/cctest
