A scientific calculator is a type of electronic calculator, usually but not always handheld, 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. In certain contexts such as higher education, scientific calculators have been superseded by graphing calculators, which offer a superset of scientific calculator functionality along with the ability to graph input data and write and store programs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. ==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 generally include: *cursor controls to edit equations and view previous calculations *hexadecimal, binary, and octal calculations, including basic Boolean math *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 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. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Scientific calculator」の詳細全文を読む スポンサード リンク
