Round() so only whole number given

This code...

		case "runtime":
			sendEvent( [
				name: 'batteryRuntimeMinutes',
				value: Integer.parseInt(value) / 60,
				unit: "min",
				descriptionText: "Remaining runtime is ${Integer.parseInt(value)} minutes"
			])
			break;

converts seconds to minutes but I need to round that to the nearest whole number. How do I accomplish that ?

I had no luck using .round() as that gave errors I can't get past.

I've used:. minutes = Math.round(minutes)

Would you mind sharing the errors? I have used .round() in the past and it has worked for me

Wrapping .ceil() should accomplish what you need I think

Not sure what the syntax would be putting inside that string though, groovy isn’t my thing

value: ((Integer.parseInt(value) / 60).round()),

produces

java.lang.NullPointerException: null on line 123 (parseVAR)

Perfect !! Worked exactly what I wanted..

		case "runtime":
        min = (Integer.parseInt(value) / 60)
        minutes = Math.round(min)
			sendEvent( [
				name: 'batteryRuntimeMinutes',
				unit: "min",
                descriptionText: "Remaining runtime is ${minutes} minutes"
			])
			break;
