WebFeb 20, 2024 · This was also presented to WG14 at the same time; WG14-N1459 makes clear that the C comparison macros are intended to support heterogeneous floating-point types. That's only realizable in the C++ wording if "sufficient additional overloads" apply. WebScalars. #. Python defines only one type of a particular data class (there is only one integer type, one floating-point type, etc.). This can be convenient in applications that don’t need to be concerned with all the ways data can be represented in a computer. For scientific computing, however, more control is often needed.
