It compiles and runs fine with g++, but when I try Microsoft's cl.exe version 19.00 I get messages such as xneural.cpp(22): error C2398: Element '1': conversion from 'double' to 'float' requires a narrowing conversion referring to the code vector<float> X { 5.1, 3.5, 1.4, 0.2, 4.9, 3.0, 1.4, 0.2, 6.2, 3.4, 5.4, 2.3, 5.9, 3.0, 5.1, 1.8 }; If I replace <float> with <double> the code compiles and runs with cl.exe.
