I'd like to generate a NaN value for a given double variable in c code running on windows.
I tried to do the following:
double d = sqrt(-1);
This code generates "-1.#IND00" instead of NaN when running on windows.
In Linux the same code generates NaN.


double d = sqrt(-1);
output => d => "-1.#IND00"

Open in new window

Windows displays a NaN as -1.#IND  here, "IND" for "indeterminate"
