The main reason for this is because a gamma of 2.2 approximately matches the power law sensitivity of human vision. The exact value that should be used varies from person to person and also depends on the lighting conditions and other factors, but a standard value had to.
HP calculators are various calculators manufactured by the Hewlett-Packard company over the years.
Their desktop models included the HP 9800 series, while their handheld models started with the HP-35. Their focus has been on high-end scientific, engineering and complex financial uses.
History[edit]
In the 1960s, Hewlett-Packard was becoming a diversified electronics company with product lines in electronic test equipment, scientific instrumentation, and medical electronics, and was just beginning its entry into computers. The corporation recognized two opportunities: it might be possible to automate the instrumentation that HP was producing, and HP's customer base were likely to buy a product that could replace the slide rules and adding machines that they were now using for computation.
With this in mind, HP built the HP 9100 desktop scientific calculator. This was a full-featured calculator that included not only standard 'adding machine' functions but also powerful capabilities to handle floating-point numbers, trigonometric functions, logarithms, exponentiation, and square roots.
Gamma (bedoor177) Mac Os X
This new calculator was well received by the customer base, but William Hewlett saw additional opportunities if the desktop calculator could be made small enough to fit into his shirt pocket. He charged his engineers with this exact goal using the size of his shirt pocket as a guide.[citation needed] The result was the HP-35 calculator. This calculator provided functionality that was revolutionary for a pocket calculator at that time.[citation needed]
Through the years, HP released several calculators that varied in their mathematical capabilities, programmability, and I/O capabilities. Some of them could be used (via HP-IL) to control the instruments other Hewlett Packard divisions produced.

| HP-27S | 1988 | The first HP pocket calculator to use algebraic notation only rather than RPN. It was a 'do all' calculator that included algebraic solver like the HP-18C, statistical, probability and time/value of money calculations. It had approximately 7 kilobytes of programmable memory which could be used for formulas or notes. The two-push 6-key letter typing system was fairly fast after a learning period.[2] |
| HP-28C | 1987 | RPN scientific graphing calculator. First HP graphing calculator, and introduced the Forth-like RPL, programmable keys, and symbolic equation solving, with 2 KB of user memory. Book-style design (flip-open cover) with keys on both interior halves. |
| HP-28S | 1988 | Expansion of HP-28C; 32 KB of user memory due to customers unexpectedly keeping programs in memory for extended periods. Introduced a file system for storing variables, functions, and user programs in the form of a multi-level tree. Like the HP-28C, this model used the 'open-book' physical design. Functionally a direct predecessor to the HP-48 series, which returned to a more traditional physical design based on the HP-41. |

| HP-41 series | 1979 | Three models in this series were released over its lifetime, the 41C, 41CV, and 41CX. The 41C had user configurable program steps and memory registers, alpha-numeric display, user programmable key mappings, and four expansion ports that could hold additional memory, an interface to HP-IL peripherals, a magnetic card reader–writer, or commercial application programs. The 41CV quintupled the amount of base memory, and the 41CX added a clock and some additional functions and memory. |
| HP-42S | 1988 | A non-expandable follow-up to the HP-41 series. It included a two line display (dot addressable) and featured built-in matrix and complex number mathematics. |

| HP 48 series | 1990 | Programmable graphic calculators, initially the SX and a year later the cheaper S, and three years later the G and GX with a faster processor and more graphical interface; SX and GX versions had expansion slots. Based on the functionality of the HP-28S, but with a return to a traditional appearance (similar to the HP-41 series). Historically one of the most popular models among engineers. Uses a filesystem first introduced on the HP-28S. Has a real-time clock and an operating system with programmable-action alarms, which could turn on the calculator and run arbitrary user programs at a user-specified time & frequency. |
