Functions

func Abs

func Abs(x int) int

Abs returns the absolute value of x.

func DegreesToRadians

func DegreesToRadians(degrees int) float64

DegreesToRadians converts degrees to the equivalent in radians.

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. Ignores NaN values. Allowing NaN values could lead to a corner case where all values can be NaN, in this case the function will return NaN as min and max.

func MinMaxInts

func MinMaxInts(values []int) (min, max int)

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

func RadiansToDegrees

func RadiansToDegrees(radians float64) int

RadiansToDegrees converts radians to the equivalent in degrees.

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.

func SimplifyRatio

func SimplifyRatio(ratio image.Point) image.Point

SimplifyRatio simplifies the given ratio.

func SplitByRatio

func SplitByRatio(n int, ratio image.Point) image.Point

SplitByRatio splits the provided number by the specified ratio.
