modulus
n 1: an integer that can be divided without remainder into the
difference between two other integers; "2 is a modulus of 5
and 9"
2: the absolute value of a complex number
3: (physics) a coefficient that expresses how much of a
specified property is possessed by a specified substance

Modulus \Mod"u*lus\, n.; pl. {Moduli}. [L., a small measure. See
{Module}, n.] (Math., Mech., & Physics)
A quantity or coefficient, or constant, which expresses the
measure of some specified force, property, or quality, as of
elasticity, strength, efficiency, etc.; a parameter.
[1913 Webster]

{Modulus of a machine}, a formula expressing the work which a
given machine can perform under the conditions involved in
its construction; the relation between the work done upon
a machine by the moving power, and that yielded at the
working points, either constantly, if its motion be
uniform, or in the interval of time which it occupies in
passing from any given velocity to the same velocity
again, if its motion be variable; -- called also the
efficiency of the machine. --Mosley. --Rankine.

{Modulus of a system of logarithms} (Math.), a number by
which all the Napierian logarithms must be multiplied to
obtain the logarithms in another system.

{Modulus of elasticity}.
(a) The measure of the elastic force of any substance,
expressed by the ratio of a stress on a given unit of the
substance to the accompanying distortion, or strain.
(b) An expression of the force (usually in terms of the
height in feet or weight in pounds of a column of the
same body) which would be necessary to elongate a
prismatic body of a transverse section equal to a given
unit, as a square inch or foot, to double, or to compress
it to half, its original length, were that degree of
elongation or compression possible, or within the limits
of elasticity; -- called also {Young's modulus}.

{Modulus of rupture}, the measure of the force necessary to
break a given substance across, as a beam, expressed by
eighteen times the load which is required to break a bar
of one inch square, supported flatwise at two points one
foot apart, and loaded in the middle between the points of
support. --Rankine.
[1913 Webster]

    "The Modulus is the remainder of the euclidean division": According to the Wikipedia article you've referenced, the modulus is the divisor in the modulo operation, not the remainder: "the modulo operation returns the remainder or signed remainder of a division, after one number is divided by another, the latter being called the modulus of the
  • How Does Modulus Divison Work - Stack Overflow
    The modulus operator takes a division statement and returns whatever is left over from that calculation, the "remaining" data, so to speak, such as 13 5 = 2 Which means, there is 3 left over, or remaining from that calculation

  • What is the result of % (modulo operator percent sign) in Python?
    The modulus is a mathematical operation, sometimes described as "clock arithmetic " I find that describing it as simply a remainder is misleading and confusing because it masks the real reason it is used so much in computer science
  • C# modulus operator - Stack Overflow
    Is it a modulus operator or a remainder operator? They differ when the divisor is negative Specifically, both compute r in D = dq + r, but modulus rounds d towards minus infinity, while remainder rounds d towards zero

    Modulus is a term used for absolute value in complex analysis, and also a term used for the thing-being-divided-by in remainder arithmetic (actually called modular arithmetic)
  • How does the % operator (modulo, remainder) work?
    You can think of the modulus operator as giving you a remainder count % 6 divides 6 out of count as many times as it can and gives you a remainder from 0 to 5 (These are all the possible remainders because you already divided out 6 as many times as you can) The elements of the array are all printed in the for loop, but every time the remainder is 5 (every 6th element), it outputs a newline
