Which operators are defined for each of the base types?

Having used C# I was surprised to discover that C++ floats did not have the modulus operator defined. Nor are the bitwise operators apparently. I decided to learn more and went looking for a chart of which base types had operators defined for them and which did not but I couldn't find anything of that nature.

I know what all the operators are and how to overload them: http://en.wikipedia.org/wiki/C%2B%2B_operators

I do not, however, know which operators are defined for each of the base types.

All operators are defined for integer types (char, short, int, long, long long and enum). For floating point types (float, double and long double), you don't have % and none of the "bitwise" operators: <<, >>, ~, &, | and ^, since they don't make much sense for floating point. For example, what do you expect from 3.3 ^ 6.8? [1] Or 1.9 % 13.4? [1] There is no "remainder" in a floating point divide, so it's hard to envisage what it actually should give.

As mentioned in the comment, fmod does a similar thing to %.

[1] These are rhetorical questions, I don't expect anyone to come up with a good answer.
