RE: TI36X Pro—Replace the batteries or just get a new one?
A 'semibug' has also been fixed in the MathPrint model. This one concerns temperature conversions on negative numbers.
Previously, in the TI36X Pro (and TI30X Pro MultiView), it was necessary to enclose negative numbers in parentheses when performing temperature conversions, otherwise, the negation would be performed after the conversion. For example, '1 °C⯈°F' would produce the result 33.8 instead of 30.2. To be fair, this was mentioned in the manual, but probably retroactively. Also, expressions such as '23 °C⯈°F' are calculated as '2  (3 °C⯈°F)' producing a result of 35.4. In the new TI30X Pro MathPrint, unit conversions seem to have a much lower priority, so that '1 °C⯈°F' and '23 °C⯈°F' both produce a result of 30.2. Strangely, the manual for the MathPrint still insists that negative numbers be placed in parentheses to do temperature conversions. This is probably left over from the previous manual! — Ian Abbott
