### Help with math for progress bar.

Posted:

**16 Jan 2019, 19:26**I'm needing to do some math for a progress bar but am unable to wrap my head around it. I'm reading the input of a temperature sensor but the input is high numbers for low temps and low numbers for high temps.

For instance,
So I need to convert these numbers for a progress bar that will reed 0c to 100c. (or get it in the ballpark)

Who here is good at math?

Thanks

Edit:

With Arduino, there is a "Map" function for changing the input to match the expected output.
Is there a similar function in AHK?

For instance,

Code: Select all

```
Temp of 34c sensor returns 380.
Temp of 4c sensor returns 660
```

With Arduino, there is a "Map" function for changing the input to match the expected output.

Code: Select all

`value = map(value, 0, 1023, 0, 255);`
