Functions

func MinMax

func MinMax(values []float64) (min, max float64)

MinMax returns the smallest and the largest value among the provided values. Returns (0, 0) if there are no values.

func Round

func Round(x float64) float64

Round returns the nearest integer, rounding half away from zero. Copied from the math package of Go 1.10 for backwards compatibility with Go 1.8 where the math.Round function doesn't exist yet.

func RoundToNonZeroPlaces

func RoundToNonZeroPlaces(f float64, places int) (float64, int)

RoundToNonZeroPlaces rounds the float up, so that it has at least the provided number of non-zero decimal places. Returns the rounded float and the number of leading decimal places that are zero. Returns the original float when places is zero. Negative places are treated as positive, so that -2 == 2.
