On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [1] [2] [3] On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
The Gauss–Legendre algorithm is an algorithm to compute the digits of π.It is notable for being rapidly convergent, with only 25 iterations producing 45 million correct digits of π.

Rapp also designed a label for the possible future ROM cartridge release of the Atari Calculator, reserving ID number CXL-4028. [37] On 27—28 April 2013, the Atari Calculator was displayed at the 14th Vintage Computer Festival Europe (VCFe) in Munich, and Vortrag Wassenberg made its presentation. Slides from this presentation were published ...
The HP-35 was 5.8 inches (150 mm) long and 3.2 inches (81 mm) wide, said to have been designed to fit into one of William Hewlett's shirt pockets. Was the first scientific calculator to fly in space in 1973. [5] HP-35 calculators were carried on the Skylab 3 and Skylab 4 flights, between July 1973 and February 1974. [6]
Let be the number of digits to which π is to be calculated. Let be the number of terms in the Taylor series (see equation 2). Let be the amount of time spent on each digit (for each term in the Taylor series). The Taylor series will converge when:
The area within a circle is equal to the radius multiplied by half the circumference, or A = r x C /2 = r x r x π.. Liu Hui argued: "Multiply one side of a hexagon by the radius (of its circumcircle), then multiply this by three, to yield the area of a dodecagon; if we cut a hexagon into a dodecagon, multiply its side by its radius, then again multiply by six, we get the area of a 24-gon; the ...
