go-calculator

Go package to calculate total, mean (average), median, sorted median, variance, range, min, max, modes, standard deviation, etc.

Getting Started

First, add the library to :

import (
    "github.com/greenpau/go-calculator"
)

Next, initialize calculator in any of the following ways:

calc, _ := calculator.NewString("1, 2, 3, 4.5, 5.4, 6, 7")

if calc == nil {
    log.Fatal("failed to initialize calculator")
}

arr := []uint64{1, 2, 3, 4, 5, 6, 7}
calc, _ := calculator.NewUint64(arr)

arr := []int64{1, 2, 3, 4, 5, 6, 7}
calc, _ := calculator.NewInt64(arr)

arr := []int{1, 2, 3, 4, 5, 6, 7}
calc, _ := calculator.NewInt(arr)

arr := []float64{1, 2, 3, 4, 5, 6, 7}
calc, _ := calculator.NewFloat64(arr)

Next, calculate total, mean (average), median, mode, range using the calc instance:

cacl.Total()
calc.StandardDeviation()
calc.Variance()
calc.Range()
calc.Max()
calc.Min()
calc.MaxWithIndices()
calc.MinWithIndices()
calc.Median(true)
calc.Median(false)
calc.Mean()
calc.Modes()

Alternatively, simply perform all calculations:

calc.RunAll()

Get the result of the calculations.

fmt.Fprintf(os.Stdout, "Total: %.2f\n", calc.Register.Total)

The Print() function helps visualize the data:
