The return value of Math.Sinh(myvalue) is still the same double.PositiveInfinity. I assume that the resource files containing the string representation for the special double values have been changed in Windows 10 so they now return that infinity symbol ∞.

If you want to keep your code the old way (which in fact is not a good idea to depend on culture-specific string representations), you may consider something like this:

double sinh = Math.Sinh(myvalue);
string v = double.IsInfinity(myvalue) ? "Infinity" : myvalue.ToString();

or simply check if the return value of ToString() is ∞ and change it accordingly.

But remember that there are some more special double values you may have to check.
