Moving average implementation for Go

Moving average implementation for Go

Usage

import "github.com/xtrcode/golang-moving-average"

ma := movingaverage.New(5) // 5 is the window size
ma.Add(10)
ma.Add(15)
ma.Add(20)
ma.Add(1)
ma.Add(1)
ma.Add(5) // This one will effectively overwrite the first value (10 in this example)
avg := ma.Avg() // Will return 8.4

ma2 := movingaverage.New(5) // 5 is the window size
ma2.AddSlice([]float64{15,20,1,1,5})
avg2 := ma2.Avg() // Will return 8.4

Partially used windows

In case you define a window of let's say 5 and only put in 2 values, the average will be based on those 2 values.

Window 5 - Values: 2, 2 - Average: 2 (not 0.8)
