Yes… but then you are reading an illegal value that JSON does not
support…
For some reason D does not seem to support this aspect of
IEEE754? I cannot find
".nans" listed on the page http://dlang.org/property.html
Because I tried supporting them in C++. It doesn't work for
various reasons. Nobody else supports them, either.
I haven't tested, but Python is supposed to throw on NaNs.
gcc has support for nans in their documentation:
https://gcc.gnu.org/onlinedocs/gcc/Other-Builtins.html
IBM Fortran supports it…
I think supporting signaling NaN is important for correctness.
