type PCG32 struct {
	// contains filtered or unexported fields
}

PCG32 represents the state of a PCG-32 random number generator.

func New() *PCG32

New creates a new PCG32 instance seeded with the current time.

func (p *PCG32) Float32() float32

Float32 generates a random float32 in the range [0.0, 1.0).

func (p *PCG32) Float64() float64

Float64 generates a random float64 in the range [0.0, 1.0).

func (p *PCG32) Int(n int) int

Int generates a random integer in the range [0, n).

func (p *PCG32) Int32() int32

Int31 generates a random 31-bit signed integer.

func (p *PCG32) Marshal() ([]byte, error)

Marshal returns the binary encoding of the current state of the random number generator.

func (p *PCG32) Next() uint32

Next generates a random 32-bit unsigned integer.

func (p *PCG32) Reset()

Reset resets the state of the random number generator to the seed value.

func (p *PCG32) Seed(seed uint64)

Seed initializes the state of the random number generator with the given seed value.

func (p *PCG32) State() (uint64, uint64)

State returns the current state of the random number generator.

func (p *PCG32) Unmarshal(data []byte) error

Unmarshal sets the state of the random number generator to the state represented by the input data.
