hi i am a novice to c++ and have been doodling with borland graphics interface with dev 188.8.131.52
below is a programme i have written which calculates the mandelbrot set (all complex number c such that |z(k)| remained bounded subject to endless iteration z(n+1)=(z(n))^2+c, z(0)=c)).
the problem with it is that when the graphics is generated, it looks like the mandelbrot set, but a grossly inaccurate representation. my guess is the limited number of significant figures c++ truncates for each calculation. any idea on increasing the number of significant figures? (something like what Window's calculator is capable of) thanks 4 the assistance!
for(int x=0; x<=800; x++)
for(int y=0; y<=600; y++)
long double x_re = -2.0 + x*0.005;
long double y_im = 1.5 - y*0.005;
long double x_0 = x_re, y_0 = y_im;
short terminating=0, i=0;
