Scientific calculators are used widely in situations that require quick access to certain mathematical functions, especially those that were once looked up in mathematical tables, such as trigonometric functions or logarithms. A few have multi-line displays, with some models from Hewlett-Packard, Texas Instruments (both US manufacturers), Casio, Sharp, and Canon (all three Japanese makers) using dot matrix displays similar to those found on graphing calculators. While most scientific calculators have traditionally used a single-line display similar to traditional pocket calculators, many of them have more digits (10 to 12), sometimes with extra digits for the floating-point exponent. letters that can be used for spelling words or including variables into an equation.programmability - see Programmable calculator.statistics and probability calculations.hexadecimal, binary, and octal calculations, including basic Boolean mathematics.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.In addition, high-end scientific calculators generally include: quick access to constants such as pi and e.exponential functions and roots beyond the square root.trigonometric functions (some including hyperbolic trigonometry).

logarithmic functions, using both base 10 and base e.The capabilities of a modern scientific calculator include: Modern scientific calculators generally have many more capabilities than the original four or five function calculator, and the capabilities differ between manufacturers and models. When scientific calculators were originally marketed they normally had only four of five capabilities (addition, subtraction, multiplication, division and square root).
