Example:

I'm trying to figure out the calculation for finding the percentage between two values that a third value is.

Example: The range is -46 to 195. The value -46 would 0%, and the value 195 would be 100% of the range. What percentage of this range is the value 65?

valueMin=-46

valueMax=195

valueNow=65

valuePercentage = ?

I have tried the following algorithm but it doesn't work :

```
const log = (txt) => console.log(txt, 'instead of 100%');
function getValueNowInPercent(valueMin, valueMax, valueNow){
const diff = valueMax - valueMin;
const percent = valueNow / diff * 100;
return percent + '%';
}
let valueMin, valueMax, valueNow;
valueMin = 0; valueNow = 50; valueMax = 100;
log(getValueNowInPercent(valueMin,valueNow,valueMax));
==> 200% instead of 100%
valueMin = -100; valueNow = 0; valueMax = 100;
log(getValueNowInPercent(valueMin,valueNow,valueMax));
==> 100% instead of 100%
valueMin = 0; valueNow = 100; valueMax = 200;
log(getValueNowInPercent(valueMin,valueNow,valueMax));
==> 200% instead of 100%
valueMin = -200; valueNow = 0; valueMax = 200;
log(getValueNowInPercent(valueMin,valueNow,valueMax));
==> 100% instead of 100%
```
