Formatting a double for output in message box

Hi,

in my program i have a message box, which informs the user that an activity has been terminated and also display the activities consumption. Something like this: 'The activity xxx has been terminated and the consumption was 4.925971e-01 kWh'

My problem: how do i get that (fairly) ugly and unreadable value '4.925971e-01' to the handy format of '0.492'?

Cheers, Mathias

You want to use sprintf, probably something like this:

sprintf('%0.3f',val);

Or, more completely:

sprintf('The activity %s has been terminated and the consumption was %0.3f kWh', activity, val);

Nice! Thanks a lot!
