The Sharp EL-5120 is a scientific programmable calculator. It has about 1 KB of total RAM available to the user, and has 4 basic operational modes: Real mode: it is the basic operational mode for directly performing standard algebraic and statistical calculations, as well as evaluating user-defined functions and numerically integrating them.
x is the argument of the complex number (angle between line to point and x-axis in polar form). The notation is less commonly used in mathematics than Euler's formula, e ix, which offers an even shorter notation for cos x + i sin x, but cis(x) is widely used as a name for this function in software libraries.
Binary coding systems of complex numbers, i.e. systems with the digits = {,}, are of practical interest. [9] Listed below are some coding systems , (all are special cases of the systems above) and resp. codes for the (decimal) numbers −1, 2, −2, i. The standard binary (which requires a sign, first line) and the "negabinary" systems (second ...
In the HP 33s, complex numbers were stored as two separate values, and the "complex" modifier was used to indicate that an operation was to treat the stack as containing complex numbers. For example, adding 12 + 34 i and 56 + 78 i involved the following keystrokes: 3 4 ↵ Enter 1 2 ↵ Enter 7 8 ↵ Enter 5 6 CMPLX + , which used up all four ...
It cost slightly less than the Fuller-Bakewell and a 1919 example is held by the Science Museum, London. [ 14 ] [ 15 ] [ 16 ] In 1962 the Whythe-Fuller complex number calculator was introduced. [ 17 ] [ 18 ] As well as being able to multiply and divide complex numbers it can convert between Cartesian and polar coordinates .
A simple arithmetic calculator was first included with Windows 1.0. [6]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.

Actually, ψ is the only solution of the functional equation (+) = + that is monotonic on R + and satisfies F(1) = −γ. This fact follows immediately from the uniqueness of the Γ function given its recurrence equation and convexity restriction. This implies the useful difference equation:
