Well, the HP feature when adding subtracting features is getting discussed
again.ie. what 0_F + 0_F is supposed to mean.

However there _is_ a temperature bug, even though I believe it is performing as documented:

Try raising a temperature to a convenient integer power:

ie 5_C^4. You get 625!!! That is _not_ right! HP does not even follow its 
own rules. 5_C should be converted to kelvins before calculating. I imagine
expressing the answer in C^4 is meaningless,  but K^4 is not meaningless, so
I imagine the answer should always be expressed in K^4.

HP hints, but doesn't state specifically that your answer will be wrong(deliberately),
they just say something about powers and temperature units.

PS 

If you think "yah so what, nobody needs powers of temperature anyways", 
then you have obviously never heard of black body radiation.
