absolute value
absolute valuen.1. The numerical value of a real number without regard to its sign. For example, the absolute value of -4 (written │-4│) is 4. Also called numerical value.2. The modulus of a complex number, equal to the square root of the sum of the squares of the real and imaginary components of the number.absolute value n 1. (Mathematics) the positive real number equal to a given real but disregarding its sign. Written | x |. Where r is positive, | r | = r = | –r | 2. (Mathematics) Also called: modulus a measure of the magnitude of a complex number, represented by the length of a line in the Argand diagram: |x + iy | = √(x2 + y2), so | 4 + 3i | = 5 ab′solute val′ue
n. 1. the magnitude of a quantity, irrespective of sign; the distance of a quantity from zero. The absolute value of a number is symbolized by two vertical lines, as |3| or |−3| is three. 2. the square root of the sum of the squares of the real and imaginary parts of a given complex number. Also called modulus. [1905–10] absolute value The value of a number without regard to its sign. For example, the absolute value of +3 (written │+3│) and the absolute value of -3 (written │-3│) are both 3.Thesaurus| Noun | 1. |  absolute value - a real number regardless of its signnumerical valuedefinite quantity - a specific measure of amountmodulus - the absolute value of a complex number |
absolute value
absolute value, magnitude of a number or other mathematical expression disregarding its sign; thus, the absolute value is positive, whether the original expression is positive or negative. In symbols, if |a| denotes the absolute value of a number a, then |a| = a for a > 0 and |a| = −a for a < 0. For example, |7|= 7 since 7 > 0 and |−7| = −(−7), or |−7| = 7, since −7 < 0.absolute value[′ab·sə‚lüt ′val·yü] Also known as magnitude. (mathematics) For a real number, the number if it is nonnegative, and the negative of the number if it is negative. Also known as numerical value. For a complex number, the square root of the sum of the squares of its real and imaginary parts. Also known as modulus. The length of a vector, disregarding its direction; the square root of the sum of the squares of its orthogonal components. MedicalSeemodulusLegalSeeValueAbsolute Value
Absolute ValueThe value of a variable without regard to whether it is positive or negative. For example, an absolute value of 6% applies whether a company's profits increase 6% or decrease by the same amount.absolute value
