Hewlett-Packard announced the HP-35 as "a fast, extremely accurate electronic slide rule"
with a solid-state memory similar to that of a computer. The HP-35
distinguished itself from its competitors by its ability to perform a
broad variety of logarithmic and trigonometric functions, to store more
intermediate solutions for later use, and to accept and display entries
in a form similar to standard scientific notation.
