Returns the multiplicative identity of this complete field.
Returns the multiplicative identity of this complete field.
Returns the additive identity of this complete field.
Returns the additive identity of this complete field.
A complete abstract field structure. Addition associates and commutes, and multiplication associates, commutes, and distributes over addition. Addition and multiplication both have an identity element, every element has an additive inverse, and every element except zero has a multiplicative inverse. Completeness implies that every Cauchy sequence of elements converges. To the extent practicable, the following axioms should hold.
Axioms for addition:
this
, then their sum 𝑎 + 𝑏 is also an element inthis
.this
.this
.this
has an elementzero
such thatzero
+ 𝑎 == 𝑎 for every element 𝑎 inthis
.this
corresponds an element -𝑎 inthis
such that 𝑎 + (-𝑎) ==zero
.Axioms for multiplication:
this
, then their product 𝑎 * 𝑏 is also an element inthis
.this
.this
.this
has an elementunit
!=zero
such thatunit
* 𝑎 == 𝑎 for every element 𝑎 inthis
.this
and 𝑎 !=zero
then there exists an element 𝑎.inverse
such that 𝑎 * 𝑎.inverse
==unit
