Scientific Calculator - Functions

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
  • 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.

Famous quotes containing the word functions:

    In today’s world parents find themselves at the mercy of a society which imposes pressures and priorities that allow neither time nor place for meaningful activities and relations between children and adults, which downgrade the role of parents and the functions of parenthood, and which prevent the parent from doing things he wants to do as a guide, friend, and companion to his children.
    Urie Bronfenbrenner (b. 1917)

    Adolescents, for all their self-involvement, are emerging from the self-centeredness of childhood. Their perception of other people has more depth. They are better equipped at appreciating others’ reasons for action, or the basis of others’ emotions. But this maturity functions in a piecemeal fashion. They show more understanding of their friends, but not of their teachers.
    Terri Apter (20th century)

    Nobody is so constituted as to be able to live everywhere and anywhere; and he who has great duties to perform, which lay claim to all his strength, has, in this respect, a very limited choice. The influence of climate upon the bodily functions ... extends so far, that a blunder in the choice of locality and climate is able not only to alienate a man from his actual duty, but also to withhold it from him altogether, so that he never even comes face to face with it.
    Friedrich Nietzsche (1844–1900)
