The calculator uses the proprietary HP Nut processor produced in a bulk CMOS process and featured continuous memory, whereby the contents of memory are preserved while the calculator is turned off. [13] Though commonplace now, this was still notable in the early 1980s, and is the origin of the "C" in the model name.

The HP Voyager series calculator are keystroke programmable, meaning that it can remember and later execute sequences of keystrokes to solve particular problems of interest to the user. These keystroke programs, in addition to performing any operation normally available on the keyboard, can also make use of conditional and unconditional ...
By 1970, a calculator could be made using just a few chips of low power consumption, allowing portable models powered from rechargeable batteries. The first handheld calculator was a 1967 prototype called Cal Tech, whose development was led by Jack Kilby at Texas Instruments in a research project to produce a portable calculator. It could add ...
A simple arithmetic calculator was first included with Windows 1.0. [5]In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Satu Mare is situated in Satu Mare County, in northwest Romania, on the river Someș, 13 km (8.1 mi) from the border with Hungary and 27 km (17 mi) from the border with Ukraine. The city is located at an altitude of 126 m (413 ft) on the Lower Someș alluvial plain , spreading out from the Administrative Palace at 25 October Square.
The carbonate compensation depth (CCD) is the depth, in the oceans, at which the rate of supply of calcium carbonates matches the rate of solvation. That is, solvation 'compensates' supply. Below the CCD solvation is faster, so that carbonate particles dissolve and the carbonate shells of animals are not preserved. Carbonate particles cannot ...
Some liken CCD to slide film (also known as positive film) and CMOS to negative film. [36] While there were larger CCD sensors made for interchangeable-lens cameras, such as the Leica M9, CCD sensors in fixed-lens cameras maxed out at 2/3″ (1/1.5″). Premium compact cameras of the time contained sensors around 1/1.7″ in size, whereas entry ...
