Class Fraction
- Cloneable, Comparable, Serializable
An immutable class representing fractions as pairs of longs.
Fractions are always maintained in reduced form.
- Serialized Form
Fraction(Fraction f) - Create a fraction with the same value as Fraction f *
|
Fraction(long num, long den) - Create a Fraction equal in value to num / den *
|
double | asDouble() - Return the value of the Fraction as a double *
|
Object | clone()
|
int | compareTo(Object other) - return a number less, equal, or greater than zero
reflecting whether this Fraction is less, equal or greater than
the value of Fraction other.
|
int | compareTo(long n) - return a number less, equal, or greater than zero
reflecting whether this Fraction is less, equal or greater than n.
|
long | denominator() - Return the denominator *
|
Fraction | dividedBy(Fraction b) - return a Fraction representing this Fraction divided by b *
|
Fraction | dividedBy(long n) - return a Fraction representing this Fraction divided by n *
|
boolean | equals(Object other)
|
boolean | equals(long n)
|
static long | gcd(long a, long b) - Compute the nonnegative greatest common divisor of a and b.
|
int | hashCode()
|
Fraction | inverse() - return a Fraction representing 1 / this Fraction *
|
Fraction | minus(Fraction b) - return a Fraction representing this Fraction minus b *
|
Fraction | minus(long n) - return a Fraction representing this Fraction minus n *
|
Fraction | negative() - return a Fraction representing the negated value of this Fraction *
|
long | numerator() - Return the numerator *
|
Fraction | plus(Fraction b) - return a Fraction representing this Fraction plus b *
|
Fraction | plus(long n) - return a Fraction representing this Fraction plus n *
|
Fraction | times(Fraction b) - return a Fraction representing this Fraction times b *
|
Fraction | times(long n) - return a Fraction representing this Fraction times n *

Fraction
public Fraction(Fraction f)
Create a fraction with the same value as Fraction f *
Fraction
public Fraction(long num,
long den)
Create a Fraction equal in value to num / den *
asDouble
public double asDouble()
Return the value of the Fraction as a double *
clone
public Object clone()
compareTo
public int compareTo(Object other)
return a number less, equal, or greater than zero
reflecting whether this Fraction is less, equal or greater than
the value of Fraction other.
compareTo
public int compareTo(long n)
return a number less, equal, or greater than zero
reflecting whether this Fraction is less, equal or greater than n.
denominator
public final long denominator()
Return the denominator *
dividedBy
public Fraction dividedBy(Fraction b)
return a Fraction representing this Fraction divided by b *
dividedBy
public Fraction dividedBy(long n)
return a Fraction representing this Fraction divided by n *
equals
public boolean equals(Object other)
equals
public boolean equals(long n)
gcd
public static long gcd(long a,
long b)

negative
public Fraction negative()
return a Fraction representing the negated value of this Fraction *
numerator
public final long numerator()
Return the numerator *
plus
public Fraction plus(Fraction b)
return a Fraction representing this Fraction plus b *
plus
public Fraction plus(long n)
return a Fraction representing this Fraction plus n *
