Where calculators have added functions (such as square root, or trigonometric functions), software algorithms are required to produce high precision results. Sometimes significant design effort is needed to fit all the desired functions in the limited memory space available in the calculator chip, with acceptable calculation time. [7]
The TI-59 was the first programmable pocket calculator where the manufacturer provided a system for sharing memory between data registers and program storage. The memory is only about twice as large as in the SR-52, but more flexible, and thus the possible number of program steps was four times as high. Contents of this memory are lost when the ...
The Extended Functions module added many functions which had long been requested by users, such as the ability to programmatically assign functions to keys, repartition memory, etc. But the most important new function was the management of extended memory: while the HP-41C could theoretically access up to 1024 registers, the early design ...
Like many Casio calculators, the FX-7000G includes a programming mode, [3] in addition to its display and graphing mode. It holds 422 bytes of programming memory, [6] less than half a kilobyte. However the calculator does allow for expanded/additional memory by a method of reducing the number of steps within a program.
The TI-84 Plus has 3 times the memory of the TI-83 Plus, and the TI-84 Plus Silver Edition has 9 times the memory of the TI-83 Plus. They both have 2.5 times the speed of the TI-83 Plus. The operating system and math functionality remain essentially the same, as does the standard link port for connecting with the rest of the TI calculator series.
However, it provides far more functions, processing power, and memory than most of those earlier models. The physical appearance and keyboard layout of the HP 35s is very different than that of its immediate predecessor, the HP 33s, but the two calculators are functionally very similar.
The HP-25 had memory space for up to 49 program steps. It was the first HP calculator which used fully merged keycodes (storing prefix key and function key together in one program location) to save memory space. Additionally there were eight storage registers and specialized scientific and statistical functions. The owner's manual came with 161 ...
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.
