Notice that only two of the relational operators, <> and =, are extended for complex numbers. The other relational operators depend on the linear ordering of the data type. In other words, all REAL, LONG or INTEGER numbers could be laid out on a number line and, of any two different numbers, one would be closer to positive infinity than the other. Since linear ordering is not defined for the complex data type, the <, >, <=, and >= operators are also not defined.
