floating-point notation



  • noun
    (written as floating point notation)
    a numerical notation in which a fractional number is represented with a point after the first digit and a power, so that any number can be stored in a standard form


  • A numeric format in which each number is represented by two numbers, and in which the decimal point is not in a fixed location. The first number, the mantissa, specifies the significant digits, while the second number, or exponent, specifies its magnitude. For example, 314,000,000 may be expressed as 3.14 × 108. Although any number, with any radix, may be represented in this manner, it is usually used only for very small or very large numbers. Also called floating-point representation, scientific notation, or exponential notation. When an E is used instead of a 10, or the radix utilized, it is also called E notation.
