Plot of
Thomae's function
on the interval (0,1). Shown are all rational points with denominator at most 200. The topmost point in the middle shows f(1/2) = 1/2
Created using the following Java code: public class Thomae {
static int gcd(int a, int b) {
while(a>0 && b>0) {
if(a>b) a -= a/b*b;
else b -= b/a*a;
}
return a>0 ? a : b;
}
public static void main(String[] args) {
int max = 200;
int width = 1280;
int height = 660;
int border = 20;
int x0 = border;
int x1 = width - border;
double dx = x1-x0;
int y0 = height - border;
double dy = -dx;
int r=5;
System.out.println("<?xml version=\"1.0\" standalone=\"no\"?>");
System.out.println("<!DOCTYPE svg PUBLIC \"-//W3C//DTD SVG 1.1//EN\" \"http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd\">");
System.out.println("<svg width=\""+ width +"\" height=\""+ height +"\" xmlns=\"http://www.w3.org/2000/svg\" version=\"1.1\">");
for(int q=1; q<max; q++) for(int p=0; p<q; p++) if(gcd(p, q) == 1) {
System.out.println(" <circle cx=\""+ (x0+dx*p/q) + "\" cy=\""+ (y0+dy*1/q) +"\" r=\""+ r +"\" fill=\"black\" stroke=\"none\" />");
}
System.out.println("</svg>");
