That did not entirely work, as in my program it isn't always only numbers inside the pow call, often I'm working with variables as well. However, a very simple change fixed it to work for...

I am writing a c++ program that has many calls of pow(input,2). I now realize that this is slowing down the program and these all should be input * input for greater speed.

The router passes off to an ethernet switch and then to my computer. This may be the problem, but I had thought the switch's only functionality was to split the internet connection, not to perform...

I am trying to set up the gnu multiple precision arithmetic library for some c++ programming I have to do.
