The difference between Absolute value and Modulus
When used as nouns, absolute value means for a complex number a+bi, the principal square root of the sum of the squares of its real and imaginary parts, \sqrt{a^2+b^2}. denoted by | |, whereas modulus means the base with respect to which a congruence is computed.

-
Absolute value as a noun (mathematics):
For a complex number a+bi, the principal square root of the sum of the squares of its real and imaginary parts, \sqrt{a^2+b^2}. Denoted by | |.
Examples:
"The absolute value x of a real number x is <math>\sqrt{x^2}</math>, which is equal to x if x is non-negative, and −x if x is negative."
-
Modulus as a noun (mathematics):
The base with respect to which a congruence is computed.
-
Modulus as a noun (mathematics):
The absolute value of a complex number.
-
Modulus as a noun (physics):
A coefficient that expresses how much of a certain property is possessed by a certain substance.
-
Modulus as a noun (computing, programming):
An operator placed between two numbers, to get the remainder of the division of those numbers.
