Functions

func Clamp

func Clamp(value, min, max float64) float64

func FloorDiv

func FloorDiv(a, b int) int

floorDiv returns the result of floor division. The difference compared to usual division is that floor division always rounds down instead of rounding towards zero.

func Radians

func Radians(degrees float64) float64
