How can I write a power function myself? http://stackoverflow.com/questions/2882706/how-can-i-write-a-power-function-myself . Calculate the root with any algorithm you like any iterative approximation like bisection or Newton method could work . Multiply..
Can I use memcpy in C++ to copy classes that have no pointers or virtual functions http://stackoverflow.com/questions/3021333/can-i-use-memcpy-in-c-to-copy-classes-that-have-no-pointers-or-virtual-functio and memcpy offers significant performance advantages over iterative assignment. I suspect it should be ok as the 'this' pointer..
