Method Detail

getZERO

public java.lang.Number getZERO()

Description copied from interface: GroupI

Returns the identity element under +

Specified by:

getZERO in interface GroupI

getONE

public java.lang.Number getONE()

Description copied from interface: RingI

Get multiplicative identity i.e. 1. Strictly speaking a ring need not have a mul indentity. However most useful ones do, and they are not all integral domains.

Specified by:

getONE in interface RingI

getInverse

public java.lang.Number getInverse(java.lang.Number num)

Description copied from interface: GroupI

Get Inverse of a number

Specified by:

getInverse in interface GroupI

add

public java.lang.Number add(java.lang.Number a,
                            java.lang.Number b)

Description copied from interface: GroupI

Get sum of the numbers

Specified by:

add in interface GroupI

sub

public java.lang.Number sub(java.lang.Number a,
                            java.lang.Number b)

Get the difference of the numbers. i.e. a + (-b)

Specified by:

sub in interface GroupI

mul

public java.lang.Number mul(java.lang.Number a,
                            java.lang.Number b)
