a "bug" in the TI86 ???? I've got a problem, in the mode "conversion"-"temp" : with the conversion 500F>0C, the calculator gives me 10 for answer, and for the conversion -140F>0C, the calculator gives me 10 for answer too. Do you find it logic ??? JPhilippe jeanph@pandemonium.fr www.pandemonium.fr/A/jeanph
