Question

Using JavaScript, I wish to convert a value between 1-100 to a corresponding value set between 1000-150000. What is the best approach for this? Comparing and multiplying / dividing array values, or is there an easier way?

Answer 1

Let’s say you would want to obtain value for 42 in value set {1000-150000}, you would need to use this formula:

((150000-1000)/100*42)+1000

Thus simpliying with:

f(x) = (1490*x)+1000

So, f(0) = 1000 , f(100) = 150000 and f(50) = 75500.

Using javascript:

function getCorrespondingValue( myValue){
     return (1490 * myValue) + 1000;
}
