About this app

This scientific calculator/complex number calculator supports all mathematical operations (addition, subtraction,

multiplication and division) and all standard mathematical functions with real, imaginary or, in general, complex numbers as their arguments.

This scientific calcultor as the most accurate and the most comprehensive Complex Number Calculator also has special features that are useful for electrical engineering, e.g., calculation of impedance.)

You can use the following in your expressions:

• Power functions, exponential and logarithmic functions
• Trigonometric functions and their Inverses
• Hyperbolic functions and their Inverses
• Gamma function, Γ
• Psi function, Ψ
• Zeta function, ζ

Press "More functions" to see trigonometric, hyperbolic and their inverses and other functions.


With it's unique and intuitive user interface, this scientific/complex number calculator computes scientific/mathematical expressions containing complexnumbers in standard (rectangular) a+bi and polar (phasor) r∠(θ) forms such as
(1/2 + 2i )(3 + 4i) + 3∠(π/4) + sin(i)cos(2 + 3i)^(4 - 2i)
and optionally converts the result or any complex number in standard form to polar and other modular forms and vice versa

(long press i or ∠ to see all forms of the calculated result).


Scientific/Complex number calculations can be performed in RAD (radians) or DEG (degrees) mode.


The results can be displayed with fixed, scientific and engineering notations.


Other features

• You can also enter functions f(x) or parametric equations p(t) and generate table of values.

This scientific calculator also lets you do statistics with one or two dimensional real data (you can also use expressions of complex numbers for data as long as they evaluate to real numbers):
• x1, x2 ,x3, ... .
•• Press Σ to calculate sum, mean, max, min, variance, sample and standard deviation, median, upper and lower quartile, etc.

• x1, y1; x2, y2; x3, y3; ... .
•• Press Σ to calculate the equation of the linear regression line and graph it.

• Calculate combinations C(n, r) and permutations P(n, r).

• Physical/Chemical/Atomic and other scientific constants.
• Easy to use unit converter (Time, Mass, Length, Velocity, and many more).

Description of additional scientific features and detailed built-in instruction is provided in the menu accompanying this

scientific calculator/complex number calculator.
