[from Latin, diminutive of modus measure]
| modulus (mj-ls) Plural moduli (m j-l) 1. A number by which two given numbers can be divided and produce the same remainder. 2. The numerical length of the vector that represents a complex number. For a complex number a + bi, the modulus is the square root of (a2 + b2). 3. The number by which a logarithm to one base must be multiplied to obtain the corresponding logarithm to another base. |
