How to make the Text item always display fractional parts of numbers?

Question

I have a Text item that display a real number:

Text { id: txt; ... }

...

txt.text: Math.round(sensor.value*10)/10

...

But if sensor.value is the integer number, it's displayed without a fractional part (35 instead 35.0). How to explicitly force txt always display a fractional part of number?

Use toPrecision method to specify the number of decimals you want to show. The method will return a string with the number formatted in the desired format

It works, but in this case numbers that < 1 display like: `0.10` instead of `0.1` – ntrsBIG Dec 04 '17 at 08:01

You can use:

var num = 5.11;
num.toFixed(1);

It will round up to 1 place of decimal.
