Module vs. absolute value

Question

Can I use a term "module" as an alternative for a term "absolute value"? For example, could this phrase be used:

"We need to raise the module of the amplitude to the second degree"

for this expression:

$p = |a|^2$

($a$ in this expression can be a real or complex number)

Answer 1

The correct term in English is modulus, the absolute value of a real or complex number.

Module is a generalization of vector spaces over rings.

In French, Italian, Spanish, and Portuguese, the same word (module, modulo, módulo) is used for both concepts.
