It looks like xdist and ydist are integers. You divide an integer by an integer, the answer is an integer. For example, if xdist=5 and ydist=10, you have 5/10, the answer is 0 (with a remainder of 5). So, if you do the multiply first, you will be (...)

I have built a plotter and want to draw a diagonal line of varying angles. It requires one motor to run slower then the other at a ratio based on the distance it has to travel compared to the other one. So I do something like this xspeed = (int) (...)

(...) I have not tried to compile this, but one thing that looks suspicious is that you are using doubles. Doubles are not supported. The compiler I have (some old version of GCC) treats doubles and floats as the same type. The compiler you're using (...) (22 years ago, 10-May-02, to lugnet.robotics.rcx.legos)

Can someone using the egcs compiler suite test the following code? It seems it doesn't compile under egcs. int main(int argc, char *argv[]) { double foo = 1.0; return foo > 0.1 ? 0 : 1; } Compiles fine under gcc 3.0.3. Regards, Michael (22 years ago, 10-May-02, to lugnet.robotics.rcx.legos)

(...) Don't know. Just made a quick download from sourceforge. Didn't install, just looked through with mc. Seems that in the mint-lib, both cmp2-files are missing. And no printf in the c library path. Regards, Michael (22 years ago, 9-May-02, to lugnet.robotics.rcx.legos)
