We predict the temperature of tomorrow with a formula,
given the temperatures of today, yesterday, and two days ago.
The program writes once sentence, in two lines:
1. the first line confirms the input;
2. the second line contains the predicted temperature.
The formula is evaluated with floats and all numbers are
shown in fixed format, with one decimal after the dot.
