Yes that's the news here, it now does all the math for you. Other search engines don't know how to do it -or- they only do the first step. Your example doesn't do what I asked. I want input to be converted to hours, minutes, and it should ideally give me both outputs: additional remaining seconds and the decimal. Wolfram Alpha's output has what I want, but it also adds what I don't:
Input interpretation
convert 5209 seconds to hours, minutes
Results
1 hour 26.82 minutes <==OK
1.447 hours <==Not asked for
Additional conversions
1 hour 26 minutes 49 seconds <==Acceptable interpretation
