WebNo, there is no such printf width specifier to print floating-point with maximum precision. Let me explain why. The maximum precision of float and double is variable, and dependent on the actual value of the float or double. Recall float and double are stored in sign.exponent.mantissa format. WebThe precision of actual floating-point operations will not exceed the 7.2 digits, so it makes no sense to give users the impression that a floating-point number has more precision. Therefore, the printf routine implements rounding after 7 decimal digits.
