Description

Push/Pop

func main() {
    clamped := maths.Clamp(2.5, 0.0, 1.0)
    // clamped == float64(1.0)
    integer := maths.ToInt(10.0)
    // integer == int(10)
}

func Atoi

func Atoi(v interface{}) (number int)

func Ceil

func Ceil[V Number](value, max V) V

Ceil returns the value if it is less-than-or-equal-to the maximum and returns the maximum otherwise

func Clamp
