type Rand ¶

type Rand struct {
	*rand.Rand
	// contains filtered or unexported fields
}

* Wrapper for the rand.Rand struct. Applies scaling defined by a Config * struct.

func NoScale(s rand.Source) (r Rand)

func (r Rand) Float32() (f float32)

func (r Rand) Int() (i int)

type Scale ¶

type Scale struct {
	Mean float64
	Std  float64
}

* Configuration for shifting the mean value and scaling the standard * deviation of random values.

func (s Scale) Float32(f float32) (rf float32)

func (s Scale) Float64(f float64) (rf float64)

func (s Scale) Int(i int) (ri int)

func (sc Scale) New(s rand.Source) (r Rand)

type Scaler ¶

type Scaler interface {
	Int(int) int
	Float32(float32) float32
	Float64(float64) float64
}

type Source ¶

type Source rand.Source

type alias for the rand package's rand.Source type
