Functions

func QuantityFrac

func QuantityFrac(numerator quantity.Quantity, denominatorExp uint8) string

QuantityFrac returns a pretty-printed representation of a quantity fraction for the given numerator and denominator's base-10 exponent.

Types

type PrettyPrinter

type PrettyPrinter interface {
	// PrettyPrint writes a pretty-printed representation of the type
	// to the given writer.
	PrettyPrint(ctx context.Context, prefix string, w io.Writer)

	// PrettyType returns a representation of the type that can be used for pretty printing.
	PrettyType() (interface{}, error)
}

PrettyPrinter is an interface for types that know how to pretty print themselves (e.g., to be displayed in a CLI).

type Quantity added in v0.2100.0

type Quantity struct {
	// contains filtered or unexported fields
}

Quantity is a quantity.Quantity wrapper for pretty-printing.

Operations over it never return an error, but just record that the Quantity has become invalid.

func NewFromQuanQuantity added in v0.2100.0

func NewFromQuanQuantity(q *quantity.Quantity) Quantity

New creates a new Quantity from a given quantity.Quantity object.

func NewQuantity added in v0.2100.0

func NewQuantity() (q Quantity)

New creates a new Quantity, initialized to zero.

func (*Quantity) Add added in v0.2100.0

func (q *Quantity) Add(n Quantity)

Add adds n to q if q is valid.

func (Quantity) IsValid added in v0.2100.0

func (q Quantity) IsValid() bool

IsValid returns true iff the q is valid.

func (*Quantity) Mul added in v0.2100.0

func (q *Quantity) Mul(n Quantity)

Mul multiplies n with q if q is valid.

func (*Quantity) Quo added in v0.2100.0

func (q *Quantity) Quo(n Quantity)

Quo divides q with n if q is valid.

func (Quantity) String added in v0.2100.0

func (q Quantity) String() string

String returns the string representation of q.

func (*Quantity) Sub added in v0.2100.0

func (q *Quantity) Sub(n Quantity)

Sub subtracts exactly n from q if q is valid.

func (Quantity) Unwrap added in v0.2100.0

func (q Quantity) Unwrap() *quantity.Quantity

Unwrap returns q's wrapped quantity.Quantity object.
