  • Scientific Notation
    Scientific notation Scientific notation (also referred to as scientific form or standard index form, or standard form in the UK) is a way of expressing numbers that are too big or too small to be conveniently written in decimal form. It is commonly used by scientists, mathematicians and engineers, in part because it can simplify certain arithmetic operations. On scientific calculators it is usually known as "SCI" display mode. In scientific notation, all numbers are written in the form Decimal notation Scientific notation m × 10n 2 2 × 100 300 3 × 102 (m times ten raised to the power of n), where the exponent n is an integer, and the coefficient m is any real number. The integer n is called the order of 4,321.768 4.321 768 × 103 [1] magnitude and the real number m is called the significand or mantissa. −53,000 −5.3 × 104 However, the term "mantissa" may cause confusion because it is the name of 6,720,000,000 6.72 × 109 the fractional part of the common logarithm. If the number is negative then a minus sign precedes m (as in ordinary decimal notation). In normalized 0.2 2 × 10−1 notation, the exponent is chosen so that the absolute value (modulus) of the 987 9.87 × 102 significand m is at least 1 but less than 10. 0.000 000 007 51 7.51 × 10−9 Decimal floating point is a computer arithmetic system closely related to scientific notation. Contents Normalized notation Engineering notation Significant figures Estimated final digit(s) E-notation Examples and other notations Order of magnitude Use of spaces Further examples of scientific notation Converting numbers Decimal to scientific Scientific to decimal Exponential Basic operations Other bases See also References External links Normalized notation Any given real number can be written in the form m × 10n in many ways: for example, 350 can be written as 3.5 × 102 or 35 × 101 or 350 × 100.
