It looks like the compiler warning: remark #2259: non-pointer conversion from "double" to "float" may lose significant bits, does not go away with the C++ static_cast<> constructs.
If you compile the following example with the -w2 option you will see that the compiler issues remark #2259 for the static_cast line. I'm user version 11.0.074 of the C++ compiler.
int main() {
double x = 3.4;
//This line will create a warning (as it should)
float y1 = x;
//This line will not create a warning (because of the cast)
float y2 = (float)(x);
//This line will create a warning (the cast should prevent it)
float y3 = static_cast(x);
cout << y1<< endl;
cout << y2 << endl;
cout << y3 << nedl;
return 0;
}
