A graphing calculator is a class of hand-held calculator that is capable of plotting graphs and solving complex functions. While there are several companies that manufacture models of graphing calculators, Hewlett-Packard is a major manufacturer.

The following table compares general and technical information for Hewlett-Packard graphing calculators:

The original hp 38g only had the function INVERSE(…) and the -1 operator was added for convenience sake in the hp 39g, released in 2000. To do this the creators had to borrow one of the existing unused characters, the 3 character, and convert it into the -1 operator. However, they forgot to change it in the CHARS view and this error has never been fixed in any of the successive models! {{cite book}}: Unknown parameter |dead-url= ignored (|url-status= suggested) (help)
