Borland C++ v3.1: pow(0,0) = 1, domain error
Watcom C++ v10.0: pow(0,0) = 1, domain error, "argument too large" [?]
Microsoft C++: pow(0,0) = 1, no error return
Linux gcc: pow(0,0) = 1, no error return
hp 15C calculator: Error 0
Matlab: 0^0 = 1, no error return
Formal mathematics: limit is undefined
