compiler warning C4244

[dellthinker]

How would i begin to fix this warning?

#include <iostream>
using namespace std;
float lbstokg(float);		// declaration

int main()
{
	float lbs;
	cout << "\nEnter your weight in pounds: ";
	cin >> lbs;
	cout << "Your weight in kilograms is " << lbstokg(lbs)
		<< endl;
	return 0;
}
//---------------------------------------------------------------------------------------------------
// lbstokg()
// converts pounds to kilograms
float lbstokg(float pounds)
{
	return 0.453592 * pounds;
}

I started this little project and curious how to avoid data loss if i ever used this in a socket type of program.

Is the error "loss of precision"?

Short answer.
0.453592 is of type double, which promotes the multiplication to double as well. You then lose precision by returning a float.
Write 0.453592f to make your floating point constant of type float.

Long answer.
Change all your floats to double
Apart from some niche environments, there's no benefit to using floats.

Thanks, I never knew this.
