Welcome to LinuxCNC.org

damn tried to load an exe file...they don't like that
here's what i have:

#include <iostream>
using namespace std;

float sfm;
float dia;
double stan = 3.82;
float rpm;
float ipr;
float ipm;

int main ()
{
/*feed/rpm gives distance per rev divided by
# of flutes -- from cradek #emc*/
int i;

cout << "mill formulas:\n(1)rpm\n(2)sfm\n(3)ipr\n(4)ipm\n selection: ";
cin >> i;
switch (i)
{
case 1:
cout << "to find rpm.\n";
cout << "sfm: ";
cin >> sfm;
cout << "tool dia: ";
cin >> dia;
cout << "recommended rpm " << (sfm*stan)/dia << "\"\n";
break;
case 2:
cout << "to find sfm.\n";
cout << "revolutions per minute: ";
cin >> rpm;
cout << "tool dia: ";
cin >> dia;
cout << "recommend sfm " << rpm*dia*.262 << "\"\n";
break;
case 3:
cout << "to find ipr.\n";
cout << "inch per minute: ";
cin >> ipm;
cout << "rpm: ";
cin >> rpm;
cout << "recommend sfm " << ipm/rpm << "\"\n";
break;
case 4:
cout << "to find ipm.\n";
cout << "inch per revolution: ";
cin >> ipr;
cout << "rpm: ";
cin >> rpm;
cout << "recommend sfm " << ipr*rpm << "\"\n";
break;
default: cout << "not a choice.\n";
}
cout << "enter zero to exit.";
cin >> i;
while (i!=0)
{cout << "enter zero to exit.";
cin >> i;}

return 0;
}

Cool, a short little basic program.

I wonder how it compares to the one on this page?

can't attach exe files...so this is what i have.

//feeds and speeds


#include <iostream>
#include "float.hpp"

using namespace std;

int main ()
{
/*feed/rpm gives distance per rev divided by
# of flutes -- from cradek #emc*/
int i;

cout << "mill formulas:\n(1)rpm\n(2)sfm\n\(3)ipr\n(4)ipm\n selection: ";
cin >> i;
switch (i)
{
case 1:
cout << "to find rpm.\n";
cout << "sfm: ";
cin >> sfm;
cout << "tool dia: ";
cin >> dia;
cout << "recommended rpm " << (sfm*stan)/dia << "\"\n";
break;
case 2:
cout << "to find sfm.\n";
cout << "revolutions per minute: ";
cin >> rpm;
cout << "tool dia: ";
cin >> dia;
cout << "recommend sfm " << rpm*dia*.262 << "\"\n";
break;
case 3:
cout << "to find ipr.\n";
cout << "inch per minute: ";
cin >> ipm;
cout << "rpm: ";
cin >> rpm;
cout << "recommend sfm " << ipm/rpm << "\"\n";
break;
case 4:
cout << "to find ipm.\n";
cout << "inch per revolution: ";
cin >> ipr;
cout << "rpm: ";
cin >> rpm;
cout << "recommend sfm " << ipr*rpm << "\"\n";
break;
default: cout << "not a choice.\n";
}
cout << "enter zero to exit.";
cin >> i;
while (i!=0)
{cout << "enter zero to exit.";
cin >> i;}

return 0;
}
