Function RoundToInteger

x/mathx/round.go:31–43

RoundToInteger rounds the given float64 to an integer.

(x float64)

// RoundToInteger rounds the given float64 to an integer.
func RoundToInteger(x float64) int {
	// If the number is 1.1 round it to the previous integer (1), if >= 1.11 round it to the next one (2).
	t := math.Trunc(x)
	odd := math.Remainder(t, 2) != 0
	d := math.Abs(x - t)
	d = Round(d, 0.5, 2) // round to 2 decimals so we can easily check 0.11 and 0.1 and 0.2.
	if d > 0.1 || (d == 0.2 && odd) {

		return int(t)
