Types

type Num

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

Num represents a half-precision floating point value (float16) stored on 16 bits.

See https://en.wikipedia.org/wiki/Half-precision_floating-point_format for more informations.

func FromBits

func FromBits(src uint16) Num

func FromLEBytes

func FromLEBytes(src []byte) Num

func Inf

func Inf() Num

func Max

func Max(first Num, rest ...Num) Num

Max returns the largest Decimal128 that was passed in the arguments

func Min

func Min(first Num, rest ...Num) Num

Min returns the smallest Decimal128 that was passed in the arguments

func NaN

func NaN() Num

func New

func New(f float32) Num

New creates a new half-precision floating point value from the provided float32 value.

func (Num) Abs

func (Num) Add

func (n Num) Add(rhs Num) Num

func (Num) Cmp

func (n Num) Cmp(other Num) int

Cmp compares the numbers represented by n and other and returns:

+1 if n > other
 0 if n == other
-1 if n < other

func (Num) Div

func (Num) Greater

func (n Num) Greater(other Num) bool

Greater returns true if the value represented by n is > other

func (Num) GreaterEqual

func (n Num) GreaterEqual(other Num) bool

GreaterEqual returns true if the value represented by n is >= other

func (n Num) Less(other Num) bool

Less returns true if the value represented by n is < other

func (Num) LessEqual

func (n Num) LessEqual(other Num) bool

LessEqual returns true if the value represented by n is <= other

func (Num) Mul
