*************************** Teres our the outputs -30 100 20 

The output would be:

 Fahrenheit Celsius -30.000 -34.444 -10.000 -23.333 10.000 -12.222 30.000 -1.111 50.000 10.000 70.000 21.111 90.000 32.222 

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

40 30 5 30 40 -5 30 40 5 

We get the output:

Starting temperature must be <= ending temperature and increment must be > 0.0 Starting temperature must be <= ending temperature and increment must be > 0.0 Fahrenheit Celsius 30.000 -1.111 35.000 1.667 40.000 4.444 

\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\\

100.5 110.4 5 

The valid output will be:

 Fahrenheit Celsius 100.500 38.056 105.500 40.833
