Created and exposed new intermediate function StrtodTrimmed(). 2019-05-25: Fix `0x` for string->double conversion when Hex Floats are allowed. Avoid integer overflow when exponents for hex floats were too big. Update version number. 2019-04-22: Fixed warning in gcc4.9. Thanks to Scott McCaskill (https://github.com/usefulcat) for the patch. 2019-04-16: Merged changes to install libraries in the correct place when using 64-bit libraries. Contributed by Jason Zaman and (independently) Dan Church (https://github.com/h3xx) 2019-03-11: Use relative includes in the library. This shouldn't have any visible effect for consumers of the library. Update version number. 2019-03-06: Fix typo in test. Update version number. 2019-03-03: Fix separator characters when they they don't fit into 8 bits. Update version number. 2019-02-16: Check correctly for _MSC_VER. Patch by Ben Boeckel 2019-01-17: Allow the library to be compiled for Emscripten. Patch by Tim Paine. 2018-09-15: Update version numbers. This also updates the shared-library version number. 2018-09-09: Fix bug where large hex literals would lose their minus sign. Added support for separator characters (which adds a new optional argument). Thus increasing the version number to 3.1.0 Added support for hexadecimal float literals. Support for more architectures. 2017-12-06: Renamed `DISALLOW_COPY_AND_ASSIGN` and `DISALLOW_IMPLICIT_CONSTRUCTORS` macros to `DC_DISALLOW_COPY_AND_ASSIGN` and `DC_DISALLOW_IMPLICIT_CONSTRUCTORS` to make it easier to integrate the library with other libraries that have similar macros. 2017-08-05: Tagged v3.0.0. Due to the directory rename switching to a new version number. The API for the library itself hasn't changed. 2017-03-04: Avoid negative shift. Fixes #41. 2016-11-17: Support RISC-V. 2016-09-10: Add fPIC flag on x86_64 if the compiler supports it. Fixes #34. 2015 and 2016: Lots of improvements to the build system. 2015: Warning fixes. 2015-05-19: Rename 'src' directory to 'double-conversion'. 2014-03-08: Update version number for cmake. Support shared libraries with cmake. Add build instructions to the README. 2014-01-12: Tagged v2.0.1. Fix compilation for ARMv8 64bit (used wrong define). Improved SConstruct file. Thanks to Milan Bouchet-Valat and Elan Ruusamäe. Fixed lots of warnings (especially on Windows). Thanks to Greg Smith. 2013-11-09: Tagged v2.0.0. String-to-Double|Float: ALLOW_LEADING_SPACES and similar flags now include new-lines, tabs and all Unicode whitespace characters. 2013-11-09: Tagged v1.1.2. Add support for ARM 64 and OsX ppc. Rewrite tests so they pass under Visual Studio. Add CMake build system support. Fix warnings. 2012-06-10: Tagged v1.1.1. Null terminate exponent buffer (only an issue when asserts are enabled). Support more architectures. 2012-02-05: Merged in Single-branch with single-precision support. Tagged v1.1 (based on b28450f33e1db493948a535d8f84e88fa211bd10). 2012-02-05: Tagged v1.0 (based on eda0196e9ac8fcdf59e92cb62885ee0af5391969).
