Why aren't static const floats allowed?

Question

I have a class which is essentially just holds a bunch of constant definitions used through my application. For some reason though, longs compile but floa

Answer 1

See Stroustrup's explanation. Relevant quote:

A class is typically declared in a header file and a header file is typically included into many translation units. However, to avoid complicated linker rules, C++ requires that every object has a unique definition. That rule would be broken if C++ allowed in-class definition of entities that needed to be stored in memory as objects. See D&E for an explanation of C++'s design tradeoffs.
