Remap Range to Another Range

remap.go

package main

import (
	"fmt"
)

func main() {
	unmappedValue := 512
	minInput := 0
	maxInput := 1023
	minOutput := 1000
	maxOutput := 3000
  
	fmt.Println(remap(unmappedValue, minOutput, maxOutput, minInput, maxInput))
}

func remap(n, toMin, toMax, fromMin, fromMax int) int {
	return (toMax - toMin) * (n - fromMin) / (fromMax - fromMin) + toMin
}

Just change to float if you want float output and input
