Method Details

rightDivide

C rightDivide(C a)

Right division.

Specified by:

rightDivide in interface MonoidElem<C extends NoncomRingElem<C>>

Parameters:

a - element.

Returns:

right, with a * right = this

rightRemainder

C rightRemainder(C a)

Right remainder.

Specified by:

rightRemainder in interface MonoidElem<C extends NoncomRingElem<C>>

Parameters:

a - element.

Returns:

r = this - a * (a/right), where a * right = this.

twosidedDivide

C[] twosidedDivide(C a)

Two-sided division.

Specified by:

twosidedDivide in interface MonoidElem<C extends NoncomRingElem<C>>

Parameters:

a - element.

Returns:

[left,right], with left * a * right = this

twosidedRemainder

C twosidedRemainder(C a)

Two-sided remainder.

Specified by:

twosidedRemainder in interface MonoidElem<C extends NoncomRingElem<C>>

Parameters:

a - element.

Returns:

r = this - (a/left) * a * (a/right), where left * a * right = this.
