Functions

func Expect

func Expect(t *testing.T, expect string, actual interface{})

func ExpectNear

func ExpectNear(t *testing.T, expect float64, actual float64, acc float64)

func Filter

func Filter(in interface{}, fn filterf) interface{}

Filter(slice, predicate func) Usage:

d := Filter(b, func(val interface{}) bool {
  return val.(int) % 4 == 0
})

func Float64Filter

func Float64Filter(slice []float64, f filterFloat64) []float64

func IntFilter

func IntFilter(slice []int, f filterInt) []int

func IntSequence

func IntSequence(begin int) func() int

Return sequence integers with the begining value as x

func Map

func Map(in interface{}, fn mapf) interface{}

Map(slice, func)

Usages:

a := []int{1, 2, 3, 4}
b := Map(a, func(val interface{}) interface{} {
	 return val.(int) * 2
})

should be [2, 4, 6, 8]

func Reduce

func Reduce(in interface{}, memo interface{}, fn reducef) interface{}

Reduce(slice, starting value, func)

Usage:

c := Reduce(b, 0, func(val interface{}, memo interface{}) interface{} {
  return memo.(int) + val.(int)
})
