For example: `[0x123, +0x45, -0x67]` are equal to `[291, 69, -103]` decimals.
- The format of float-point numbers is fully compatible with C/C++ format.
If a modern C++ compiler is used the parser accepts hexadecimal and special
float-point literals as well:
floating-point literals as well:
`[-1.0, 2., .3e0, 3.e4, 0x21.34p-5, -inf, nan]`.
The exponent suffix of hexadecimal float-point number is mandatory.
Extended float-point support was tested with:
The following conventions for floating-point numbers are used:
- The exponent suffix of hexadecimal floating-point number is mandatory.
- Parsed `NaN` converted to unsigned IEEE-754 `quiet-NaN` value.
Extended floating-point support was tested with:
- x64 Windows: `MSVC2015` and higher.
- x64 Linux: `LLVM 6.0`, `GCC 4.9` and higher.
For details, see [Use in C++](@ref flatbuffers_guide_use_cpp) section.
- For compatibility with a JSON lint tool all numeric literals of scalar
fields can be wrapped to quoted string:
`"1", "2.0", "0x48A", "0x0C.0Ep-1", "-inf", "true"`.
