Types ¶

type Fraction ¶

type Fraction struct {
	Denominator int
	Numerator   int
}

Fraction struct stores the numerator and denominator of a fraction as integers.

func FromFloat ¶

func FromFloat(n float64) *Fraction

FromFloat converts a float64 to a fraction.

func NewFraction ¶

func NewFraction(n, d int) *Fraction

NewFraction returns new fraction with n as numerator and d as denominator. Reduces fraction if possible. Returns an empty fraction (0/1) if d is less than 1.

func Zero ¶

func Zero() *Fraction

Zero returns an empty fraction equal to 0/1.

func (*Fraction) Add ¶

func (f *Fraction) Add(v *Fraction) *Fraction

Add adds a fraction to f.

func (*Fraction) AddFloat ¶

func (f *Fraction) AddFloat(n float64) *Fraction

AddFloat adds a floating point number to f.

func (*Fraction) AddInt ¶

func (f *Fraction) AddInt(n, d int) *Fraction

AddInt adds n/d to f.

func (*Fraction) Copy ¶

func (f *Fraction) Copy() *Fraction

Copy returns a deep copy of f.

func (*Fraction) Divide ¶

func (f *Fraction) Divide(v *Fraction) *Fraction

Divide divides f by v.

func (*Fraction) DivideFloat ¶

func (f *Fraction) DivideFloat(n float64) *Fraction

DivideFloat divides f by a floating point number.

func (*Fraction) DivideInt ¶

func (f *Fraction) DivideInt(n, d int) *Fraction

DivideInt divides f by n/d.

func (*Fraction) Equals ¶

func (f *Fraction) Equals(v *Fraction) bool

Equals returns true if two fractions are equal.

func (*Fraction) Float ¶

func (f *Fraction) Float() float64

Float returns numerator/denominator.

func (*Fraction) Greater ¶

func (f *Fraction) Greater(v *Fraction) bool

Greater returns true if f is greater than v.

func (*Fraction) GreaterOrEqual ¶

func (f *Fraction) GreaterOrEqual(v *Fraction) bool

GreaterOrEqual returns true if f is greater than or equal to v.

func (*Fraction) Less ¶

func (f *Fraction) Less(v *Fraction) bool

Less returns true if f is less than v.

func (*Fraction) LessOrEqual ¶

func (f *Fraction) LessOrEqual(v *Fraction) bool

LessOrEqual returns true if f is less than or equal to v.

func (*Fraction) Multiply ¶

func (f *Fraction) Multiply(v *Fraction) *Fraction

Multiply multiplies v times f.

func (*Fraction) MultiplyFloat ¶

func (f *Fraction) MultiplyFloat(n float64) *Fraction

MultiplyFloat multiplies f by a floating point number.

func (*Fraction) MultiplyInt ¶

func (f *Fraction) MultiplyInt(n, d int) *Fraction

MultiplyInt multiplies f by n/d.

func (*Fraction) String ¶

func (f *Fraction) String() string

String returns fraction formatted as a string.

func (*Fraction) Subtract ¶

func (f *Fraction) Subtract(v *Fraction, abs bool) *Fraction

Subtract subtracts a fraction from f. Returns the absolute value of the result if abs is true.

func (*Fraction) SubtractFloat ¶

func (f *Fraction) SubtractFloat(n float64, abs bool) *Fraction

SubtractFloat subtracts a floating point number from f. Returns the absolute value of the result if abs is true.

func (*Fraction) SubtractInt ¶

func (f *Fraction) SubtractInt(n, d int, abs bool) *Fraction

SubtractInt subtracts n/d from f. Returns the absolute value of the result if abs is true.
