Handy custom functions in TI Nspire for temperature conversion

The TI Nspire provided comprehensive unit conversion and one of the most used is working between Celsius and Fahrenheit. However, accessing these in the Calculator page is not quite straightforward. To save some keystrokes, some handy functions can easily be written in the MyLib folder to call these built-in functions.

While it looks like a piece of cake, there seems to be some quirks on the program editor that inadvertently changed the program code. And no matter how the line of function below being typed, it turned into something that will cause syntax error after Check Syntax and Store.

tmpcnv2

This is the original program as typed in:
tmpcnv1a

..being changed to weird code after “Check Syntax and Store”:
tmpcnv1b

A simple solution is to just add an one in between and the compiler will not monkey with the code anymore.
tmpcnv1c
