type Float

type Float struct {

Float is a nullable float64. It does not consider zero values to be null. It will decode to null, not zero, if null.

func FloatFrom

func FloatFrom(f float64) Float

FloatFrom creates a new Float that will always be valid.

func FloatFromPtr

func FloatFromPtr(f *float64) Float

FloatFromPtr creates a new Float that be null if f is nil.

func NewFloat

func NewFloat(f float64, valid bool) Float

NewFloat creates a new Float

func (Float) FullString

func (f Float) FullString() string

FullString returns float as string in full precision

func (Float) IsZero

func (f Float) IsZero() bool

IsZero returns true for invalid Floats, for future omitempty support (Go 1.4?) A non-null Float with a 0 value will not be considered zero.

func (Float) MarshalJSON

func (f Float) MarshalJSON() ([]byte, error)

MarshalJSON implements json.Marshaler. It will encode null if this Float is null.

func (Float) MarshalText

func (f Float) MarshalText() ([]byte, error)

MarshalText implements encoding.TextMarshaler. It will encode a blank string if this Float is null.

func (Float) Ptr

func (f Float) Ptr() *float64

Ptr returns a pointer to this Float's value, or a nil pointer if this Float is null.

func (*Float) SetValid

func (f *Float) SetValid(n float64)

SetValid changes this Float's value and also sets it to be non-null.

func (Float) String

func (f Float) String() string

MarshalText implements encoding.TextMarshaler. It will encode a blank string if this Float is null.

func (*Float) UnmarshalJSON

func (f *Float) UnmarshalJSON(data []byte) error

UnmarshalJSON implements json.Unmarshaler. It supports number and null input. 0 will not be considered a null Float. It also supports unmarshalling a sql.NullFloat64.

func (*Float) UnmarshalText

func (f *Float) UnmarshalText(text []byte) error

UnmarshalText implements encoding.TextUnmarshaler. It will unmarshal to a null Float if the input is a blank or not an integer. It will return an error if the input is not an integer, blank, or "null".
