Why do all the temp sensors truncate the numbers instead of round?

I ran into the same issue when trying to report a battery voltage. At some point, I found a reply around here from ST stating its an issue in mobileapp(s).

Temperature displayed in the Smart Things App

The change from double to integer is made at the mobile app level. We’re currently talking about how to get rid of that with preferences to give the user the option to use decimals. By default they will always come without the decimal.

I sorta got around it by separating out the integer and fractional components and then re-combining in a string format. However even the string cannot contain the format x.x, you have to use some other delimiter. So 77,9 will work, or put space between the decimal point and number; 77. 9

 	def intVdc = (data.topaz.battery_level.toFloat()/1000).round(0)
def fracVdc = (data.topaz.battery_level.mod(intVdc*1000)).toInteger()   
    intVdc = intVdc.toInteger()

    sendEvent(name: 'batteryvolts', value: "$intVdc. $fracVdc" )
