Operation Index

This section is a quick reference for all functions and operations and their formulas, where appropriate. The listing is in alphabetical order by the function's name. This name is the one used in program lines. For example, the function named FIX n is executed as 8(1) n.

Nonprogrammable functions have their names in key boxes. For example, .

Non–letter and Greek characters are alphabetized before all the letters; function names preceded by arrows (for example, DEG) are alphabetized as if the arrow were not there.

The last column, marked , refers to notes at the end of the table.
