loss of precision while using CString Format function

[austinium]

Hi,

iam facing issues with loss of precision when using CString's Format function, heres a code snippet.

double func(double dvar)
{
	return dvar*0.00277777778;
}
//code
	CString tempStr;
	double var = func(10);	//var is 0.0277777778
	tempStr.Format("%G",var);	//tempStr is 0.0277778

How do i prevent this loss of precision?

thanks in advance
