Parse large floats as infinity (#1349) (#1353) Return 1.9.1 functionality where values too large to fit in double are converted to positive or negative infinity. Commit 645cd04 changed functionality so that large floats cause parse error, while version 1.9.1 accepted them as infinite. This is problematic because writer outputs infinity values as `1e+9999`, which could no longer be parsed back. Fixed also legacy Reader even though it did not parse large values even before breaking change, due to problematic output/parse asymmetry. `>>` operator sets value to numeric_limits::max/lowest value if representation is too large to fit to double. [1][2] In macos value appears to be parsed to infinity. > | value in *val* | description | > |--------------------------|-------------| > | numeric_limits::max() | The sequence represents a value too large for the type of val | > | numeric_limits::lowest() | The sequence represents a value too large negative for the type of val | [1] https://www.cplusplus.com/reference/istream/istream/operator%3E%3E/ [2] https://www.cplusplus.com/reference/locale/num_get/get/ Signed-off-by: Tero Kinnunen <tero.kinnunen@vaisala.com> Co-authored-by: Tero Kinnunen <tero.kinnunen@vaisala.com>
JSON is a lightweight data-interchange format. It can represent numbers, strings, ordered sequences of values, and collections of name/value pairs.
JsonCpp is a C++ library that allows manipulating JSON values, including serialization and deserialization to and from strings. It can also preserve existing comment in unserialization/serialization steps, making it a convenient format to store user input files.
JsonCpp documentation is generated using Doxygen.
1.y.z is built with C++11.0.y.z can be used with older compilers.00.11.z can be used both in old and new compilers.The branch 00.11.zis a new branch, its major version number 00 is to show that it is different from 0.y.z and 1.y.z, the main purpose of this branch is to make a balance between the other two branches. Thus, users can use some new features in this new branch that introduced in 1.y.z, but can hardly applied into 0.y.z.
You can download and install JsonCpp using the vcpkg dependency manager:
git clone https://github.com/Microsoft/vcpkg.git cd vcpkg ./bootstrap-vcpkg.sh ./vcpkg integrate install ./vcpkg install jsoncpp
The JsonCpp port in vcpkg is kept up to date by Microsoft team members and community contributors. If the version is out of date, please create an issue or pull request on the vcpkg repository.

If you are using the Meson Build System, then you can get a wrap file by downloading it from Meson WrapDB, or simply use meson wrap install jsoncpp.
