Functions ¶

func Butterfly ¶

func Butterfly(x0 float64, x1 float64) (y0 float64, y1 float64)

Butterfly performs a 2-dimensional butterfly operation: computes (x0+x1, x0-x1). Demonstrates multiple named return values.

func CriticalLine ¶

func CriticalLine(t float64) complex128

CriticalLine returns the complex value 0.5 + it on Riemann's critical line. Demonstrates returning complex values.

func Interval ¶

func Interval(start uint64, size uint64) (uint64, uint64)

Interval returns the (start, end) of an interval with the given start and size. Demonstrates multiple unnamed return values.

func Septuple ¶

func Septuple(byte) [7]byte

Septuple returns an array of seven of the given byte. Demonstrates returning array values.

Types ¶

type Struct ¶

type Struct struct {
	Word  uint16
	Point [2]float64
	Quad  uint64
}

Struct is used to demonstrate writing struct return values.

func NewStruct ¶

func NewStruct(w uint16, p [2]float64, q uint64) Struct

NewStruct initializes a Struct value. Demonstrates returning struct values.
