modulus

9.1
A whole number that divides exactly into the difference between two whole numbers
  • noun
  • /ˈmɒdʒʊləs/
  • Specialized
translation icon : módulo
  • To find the result of the operation, you must identify the modulus that perfectly divides the difference between the two integers.

Examples

  • Locally available river sand (specific gravity of 2.5 and fineness modulus of 3) was used as fine aggregate.

    Academic text (2017)
  • The fine aggregate is saturated surface-dry clean river sand (fineness modulus = 2.6).

    Academic text (2017)
  • If N is the modulus, an integer number represented in k bits, and A and B are integer numbers that are each represented in k bits, then the product A x B is formed by using the binary representation of B in k bits.

    Academic text (1999)
  • In number theory, the modulus is the integer that divides the difference between two whole numbers without leaving a remainder.

  • When calculating the modulus of 12 and 8, the result is 4 since 4 is the integer that divides evenly into their difference.

Etymology

Modulus comes from the Latin modus ('measure') with the ending -ulus ('small'), so it means a number used to 'measure' differences. That's why in number theory a modulus is the number you use to measure cycles or to say two numbers are the same when you count by that number.
