Complex numbers not in fundamental class?

Hi Community
Since a complex number is 1x1 array, why isn't in fundamental class type of datas?

Complex is an attribute, not a class. If you made it a class, you would need a separate class for each different datatype that can be complex -- single, double, int8, uint8, int16, uint16, int32, uint32, int64, uint64. (Complex logical and complex char get converted to double precision.)
Meanwhile you would still need isnumeric() and issingle() and isdouble() and isinteger() to continue to work on the values. What would your inheritence hierarchy be?
