Scientific Calculator ++

designed to calculate problems in science, engineering, and mathematics

"Scientific calculator ++" is an android application designed to calculate problems in science, engineering, and mathematics. They have almost completely replaced slide rules in almost all traditional applications, and are widely used in both education and professional settings.

For higher education, "scientific calculator++" have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs for the device. There is also some overlap with the financial calculator market.

Scientific calculator with complex numbers and graphing of user-defined functions.

[Main duties]

- Move the cursor by pressing the screen, and slide your finger to scroll

- Define the types of decimals and thousands separator parameters

- Horizontal Screen Display

- Check your input with vibration and orange color

Functions

Modern scientific calculators generally have many more features than a standard four or five-function calculator, and the feature set differs between manufacturers and models; however, the defining features of a scientific calculator include:

scientific notation

floating point arithmetic

logarithmic functions, using both base 10 and base e

trigonometric functions (some including hyperbolic trigonometry)

exponential functions and roots beyond the square root

quick access to constants such as pi and e

In addition, high-end scientific calculators will include:

hexadecimal, binary, and octal calculations, including basic Boolean math

complex numbers

fractions

statistics and probability calculations

programmability — see Programmable calculator

equation solving

calculus

letters that can be used for spelling words or including variables into an equation

conversion of units

physical constants

While most scientific models have traditionally used a single-line display similar to traditional pocket calculators, many of them have at the very least more digits (10 to 12), sometimes with extra digits for the floating point exponent. A few have multi-line displays, with some recent models from Hewlett-Packard, Texas Instruments, Casio, Sharp, and Canon using dot matrix displays similar to those found on graphing calculators.

Uses

Scientific calculators are used widely in any situation where quick access to certain mathematical functions is needed, especially those such as trigonometric functions that were once traditionally looked up in tables; they are also used in situations requiring back-of-the-envelope calculations of very large numbers, as in some aspects of astronomy, physics, and chemistry.

They are very often required for math classes from the junior high school level through college, and are generally either permitted or required on many standardized tests covering math and science subjects; as a result, many are sold into educational markets to cover this demand, and some high-end models include features making it easier to translate the problem on a textbook page into calculator input, from allowing explicit operator precedence using parentheses to providing a method for the user to enter an entire problem in as it is written on the page using simple formatting tools.
