Thank you for answering!
I haven't got to the wiki yet, just the forum.
I have shut IPv6, but might have to reconnect to see the difference, will tell you anyway. Thanks!
When you say "explicitly linked the math library" do you mean #include <math.h> or something else? Because that's done.
I didn't try every function in math.h, but I assume that some are working since the "round" function seems OK.
I'm able to find another way, but that won't be very efficient. If you have another hint for me, I'll take it?
Thanks to the both of you!
Have a nice day
