In September 1981, the Atari Calculator was marketed in the Atari Connection magazine, in the section for new business and professional applications: [8]. More than a simple handheld calculator, the ATARI Calculator combines features found in scientific, business, and statistical calculators.
[3] [4] Clive Sinclair wanted to design a calculator to compete with the HP-35 using this series of chips. Despite scepticism about the feasibility of the project from Texas Instruments engineers, Nigel Searle was able to design algorithms that sacrificed some speed and accuracy in order to implement scientific functions [ 4 ] on the TMS0805 ...
"A base is a natural number B whose powers (B multiplied by itself some number of times) are specially designated within a numerical system." [1]: 38 The term is not equivalent to radix, as it applies to all numerical notation systems (not just positional ones with a radix) and most systems of spoken numbers. [1]
SR-50 (1974) Printed circuit board. Data code 035: 3rd week 1975. The SR-50 was Texas Instruments' first scientific pocket calculator with trigonometric and logarithm functions. . It enhanced their earlier SR-10 and SR-11 calculators, introduced in 1973, which had featured scientific notation, squares, square root, and reciprocals, but had no trig or log functions, and lacked other featur
HP 48G calculator, uses RPL RPL [5] is a handheld calculator operating system and application programming language used on Hewlett-Packard 's scientific graphing RPN (Reverse Polish Notation) calculators of the HP 28 , 48 , 49 and 50 series, but it is also usable on non-RPN calculators, such as the 38 , 39 and 40 series.
This calculator program has accepted input in infix notation, and returned the answer , ¯. Here the comma is a decimal separator. Here the comma is a decimal separator. Infix notation is a method similar to immediate execution with AESH and/or AESP, but unary operations are input into the calculator in the same order as they are written on paper.
The HP 30b (NW238AA, variously codenamed "Big Euro", "Mid Euro" and "Fox" [1]) is a programmable [2] financial calculator from HP which was released on 7 January 2010. [3] The HP 30b is an advanced version of the HP's prior model HP 20b.
Engineering notation or engineering form (also technical notation) is a version of scientific notation in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10 3 instead of 5.31×10 5 (but on calculator displays written without the ×10 to save space).
