func Abs ¶

func Abs(x float64) float64

Abs returns the absolute value of x.

Special cases are:

Abs(±Inf) = +Inf
Abs(NaN) = NaN

func CopySign ¶

func CopySign(x, y float64) float64

CopySign returns a value with the magnitude of x and the sign of y.

func Float64Bits ¶

func Float64Bits(f float64) uint64

Float64Bits returns the IEEE 754 binary representation of f.

func Float64FromBits ¶

func Float64FromBits(b uint64) float64

Float64FromBits returns the floating point number corresponding the IEEE 754 binary representation b.

func IsFinite ¶

func IsFinite(f float64) bool

IsFinite reports whether f is neither NaN nor an infinity.

func IsInf ¶

func IsInf(f float64) bool

IsInf reports whether f is an infinity.

func IsNaN ¶

func IsNaN(f float64) (is bool)

IsNaN reports whether f is an IEEE 754 “not-a-number” value.
