/// <summary>
/// Returns the type that results from applying the NumPy

///
/// Type promotion in NumPy works similarly to the rules in languages
/// like C++, with some slight differences. When both scalars and
/// arrays are used, the array’s type takes precedence and the actual value
/// of the scalar is taken into account.
///
/// For example, calculating 3*a, where a is an array of 32-bit floats,
/// intuitively should result in a 32-bit float output. If the 3 is a
/// 32-bit integer, the NumPy rules indicate it can’t convert losslessly
/// into a 32-bit float, so a 64-bit float should be the result type.
/// By examining the value of the constant, ‘3’, we see that it fits in
/// an 8-bit integer, which can be cast losslessly into the 32-bit float.
///
/// Notes
///
/// The specific algorithm used is as follows.
///
/// Categories are determined by first checking which of boolean,
/// integer (int/uint), or floating point (float/complex) the maximum
/// kind of all the arrays and the scalars are.
///
/// If there are only scalars or the maximum category of the scalars
/// is higher than the maximum category of the arrays,
/// the data types are combined with promote_types
/// to produce the return value.
///
/// Otherwise, min_scalar_type is called on each array, and
/// the resulting data types are all combined with promote_types
/// to produce the return value.
///
/// The set of int values is not a subset of the uint values for types
/// with the same number of bits, something not reflected in
/// min_scalar_type, but handled as a special case in result_type.
