cout problem

[rucafe]

This is probably a simple problem but I can't figure it out.

const int phantom_size = 20; //mm
	const int phantom_res = 200;
	float voxel_size = phantom_size/phantom_res;
	cout << "voxel_size = " << voxel_size << " mm^3" << endl;

When I compile this the output is voxel_size = 0 mm^3 no matter what values I have for phantom_size and phantom_res. Why is the output doing this?????

[bcthund]

float voxel_size = float(phantom_size)/float(phantom_res);

or

const float phantom_size = 20; //mm
const float phantom_res = 200;
