Field Details

ZERO

static final Rational ZERO

ONE

static final Rational ONE

NEGATIVE_ONE

static final Rational NEGATIVE_ONE

TEN

static final Rational TEN

PI

static final Rational PI

Method Details

arithmetic

static Arithmetic<Rational,Rational> arithmetic()

of

static Rational of(long numerator,
 long denominator)

of

static Rational of(long numerator)

of

static Rational of(BigInteger numerator,
 BigInteger denominator)

of

static Rational of(BigInteger numerator)

of

static Rational of(BigDecimal decimal)

parse

static Rational parse(String number)

from

static Rational from(Double value)

equals

boolean equals(Object other)

Overrides:

equals in class Object

hashCode

int hashCode()

Overrides:

hashCode in class Object

plus

default Rational plus(long other)

minus

default Rational minus(Rational other)

Specified by:

minus in interface AdditionGroup<Rational>

minus

default Rational minus(long other)

times

default Rational times(long other)

over

default Rational over(Rational other)

Specified by:

over in interface MultiplicationGroup<Rational>

over

default Rational over(long other)

abs

default Rational abs()

Description copied from interface: Signed

Returns the absolute value of this instance.

Specified by:

abs in interface AdditionGroup<Rational>

Specified by:

abs in interface Signed<Rational>

Returns:

Signed.negate() when this value is negative; otherwise this instance

numerator

Int numerator()

denominator

Int denominator()

square

Rational square()

cube

Rational cube()

toBigDecimal

BigDecimal toBigDecimal()

toLong

long toLong()

The equivalent Long value. This is equivalent to divide the numerator by the denominator using long division, discarding the remainder. If isWhole() is true, and the value fits in a Long, this value is the numerator.

Returns:

the equivalent long value.

floor

Rational floor()

ceil

Rational ceil()

isWhole

boolean isWhole()

raisedTo

default Rational raisedTo(int exponent)

isNegativeOne

default boolean isNegativeOne()

isOne

default boolean isOne()

Description copied from interface: MultiplicationMonoid

Checks whether is One.

Specified by:

isOne in interface MultiplicationMonoid<Rational>

Returns:

the result of isOne

isZero

boolean isZero()

Description copied from interface: Signed

Tests if this value is zero.

Specified by:

isZero in interface AdditionMonoid<Rational>

Specified by:

isZero in interface Signed<Rational>

Returns:

true if Signed.sign() returns 0; false otherwise

increment

Rational increment()

decrement

Rational decrement()
