Method Detail

getInstance

public static BigRealField getInstance()
Get the unique instance.

Returns:
the unique instance

getOne

public BigReal getOne()
Get the multiplicative identity of the field.

The multiplicative identity is the element e1 of the field such that for all elements a of the field, the equalities a × e1 = e1 × a = a hold.

Specified by:
getOne in interface Field<BigReal>
Returns:
multiplicative identity of the field

getZero

public BigReal getZero()
Get the additive identity of the field.

The additive identity is the element e0 of the field such that for all elements a of the field, the equalities a + e0 = e0 + a = a hold.

Specified by:
getZero in interface Field<BigReal>
Returns:
additive identity of the field

getRuntimeClass

public Class<? extends FieldElement<BigReal>> getRuntimeClass()
Returns the runtime class of the FieldElement.

Specified by:
getRuntimeClass in interface Field<BigReal>
Returns:
The Class object that represents the runtime class of this object.
