Method Detail

add

public Number add(Number n)

Description copied from class: Number

Adds this Number to another Number n and returns the result.

If this Number and n are of the same type, returned result must be of that type.
If this and n are of different types, returned result must be as narrow as possible.
But in all cases add(n) and n.add(this) must return the same Number.

Specified by:

add in class Number

mult

public Number mult(Number n)

Description copied from class: Number

Multiplies this Number by another Number n and returns the result.

If this Number and n are of the same type, returned result must be of that type.
If this and n are of different types, returned result must be as narrow as possible.
But in all cases mult(n) and n.mult(this) must return the same Number.

Specified by:

mult in class Number

inverse

public Number inverse()

Description copied from class: Number

Returns the multiplicative inverse of this Number.

For any Number n, if inverse() is defined, n.inverse().inverse() must be equal to n.
Also n.inverse().mult(n).value() must be 1.0

Specified by:

inverse in class Number

value

public float value()

Description copied from class: Number

Returns the float value of this Number.

Specified by:

value in class Number

toString

public java.lang.String toString()

String representation of this Number
