# Modulus

Modulus may refer to:

• Modulus (gastropod) a genus of small sea snails
• Modulus (algebraic number theory), a formal product of places of a number field
• The absolute value of a real or complex number ( |a | )
• Modular arithmetic, the modulus being the value at which numbers "wrap around"
• Modulus of continuity, a function gauging the uniform continuity of a function
• Elastic modulus, a measure of stiffness
• Young's modulus, a specific elastic modulus
• The modular function in theory of Haar measure, often called simply the modulus.
• Modulus Guitars, musical instrument manufacturer
• Modulus robot, a household robot
• The modulo operator (`%`, `mod`, etc.) of various programming languages
• Modulus watch brand in Switzerland. Now called Auguste Reymond watches.

Moduli, the plural form may refer to:

• Moduli (physics), scalar fields for which the potential energy function has continuous families of global minima
