> ISO C standard for Complex numbers states that the abs() must be obtained with a hypot() function to avoid over and underflows. The function is correctly hand-coded in the current iteration of Complex, but I see no need for this. Propose replacing with java.lang.Math.hypot to make the code and its conformance to ISO C more easily comprehensible.
