var EpsilonVeryClose = 1e-16

func AbsInt64(x int64) int64

AbsInt64 returns the absolute value of x.

func Alike(a, b float64) bool

Alike returns true if a,b is the same exactly (no tolerance) or both NaN

func Close(a, b float64) bool

Close returns true if |a-b| < 1e14

func SoClose(a, b, e float64) bool

SoClose is an alias of Tolerance

func Tolerance(a, b, e float64) bool

Tolerance returns true if |a-b| < e e usually can be set with Epsilon(1e-6)

func TruncPrecision(x float64, n int) float64

TruncPrecision returns the float value of x, with case n >= 0

the maximum n bits precision.

case n < 0

-n bits of the magnitude of x trunked

Special cases are:

Trunc(±0) = ±0
Trunc(±Inf) = ±Inf
Trunc(NaN) = NaN

func VeryClose(a, b float64) bool

VeryClose returns true if |a-b| < 1e16
