Is printf("%.1f", -0.01) required to produce 0.0, -0.0, or are both acceptable?
Subclause says that when the + flag is not specified, the result begins with a sign only when a negative value is converted. The description of the f conversion (also e and E) says that the value is rounded to the appropriate number of digits. Is the value used to determine the sign of the result the value before or after rounding?
As specified in subclause for the + flag, a negative value is being converted, so a minus sign is required. The intent is that the sign is determined prior to conversion.
