Online Full Screen Scientific Calculator – A digital calculator is a type of electronic calculator, usually but not always handheld, designed to calculate problems in science, engineering, and mathematics. They have completely replaced slide rules in traditional applications, and are widely used in both education and professional settings.
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 generally include:
- cursor controls to edit equations and view previous calculations (some calculators such as the LCD-8310, badge engineered under both Olympia and United Office keep the number of the previous result on-screen for convenience while the new calculation is being entered.
- hexadecimal, binary, and octal calculations, including basic Boolean mathematics
- complex numbers
- fractions calculations
- statistics and probability calculations
- programmability — see Programmable calculator
- equation solving
- matrix calculations
- calculus
- letters that can be used for spelling words or including variables into an equation
- conversion of units
- physical constants
