All these cases are completely different. Let's imagine other example:

int i = 2^2; - this will be square of 2
double d = 2.0^2; - this will be square root of 2

I.e. the same symbol for not the same operations in almost the same
expressions (which differ in only the type of operands).
I understand that my example is exaggerated, but it shows what
situation I beware of.
