 The following rules are applied to determine the result type:
 
 * If either of the base or exponent are of a floating point type, the result will be a double
-* Otherwise, if either the base of the exponent are 64-bit (long or unsigned long), the result will be a long
-* Otherwise, the result will be a 32-bit integer (all other numeric types, including int, short and byte)

 However, a more likely outcome of very large non-floating point values is numerical overflow.
