rjmccall added a comment.
This property adheres to a function definition, so it seems to me that an explicit *instantiation* ought to preserve it from the instantiated template definition, but an explicit *specialization* ought to be independent.
i.e.
#pragma float_control(precise, on, push)
template <typename Ty>
float func2(Ty) {
float f1 = 1.0f, f2 = 3.0f;
return f1 + f2 * 2.0f;
}
#pragma float_control(pop)
template float func2<int>(int); // precise
template <> float func2<long>(long) { ... } // not precise
