RND variable math modified to allow to a specific decimal place

[jshimota]

A feature request maybe?
I wrote a rule to store temp values from various devices with 1, 2 and 3 decimal places to variables. Then using Variables math I added them up and divided by my variable quantity. Call it a poor mans Average Plus app

When I went to use the Variable math RND function, I had expected it to ask what decimal place I was rnd'ing too. However it rnd'ed me to a whole number. I was hoping to rnd to a 10th. so 74.123 degrees would be 74.1. The result I got was simply 74 . Luckily, the tile I am displaying the value into allowed me to set the decimal place.

You can do this with a combination of round (which is always an integer, as you've discovered) and variable math. See here for a recent discussion on how:

Formating Variable

Is it possible to format variable in RM? This is what I have now: [image] But I would like to display only 2 digits after the dot. I can convert this number to Integer but Decimal with 2 digits after the dot is desired.

Brilliant!

What do you use such precise temperature measurements for?

My wife can detect temperature variations that small from what she desires as the house temperature.
