Hi folks, often times in science one expresses a value (say
1.03789291) and its error (say 0.00089) in a short way by parentheses
like so: 1.0379(9)
One can vary things a bit, but let's take the simplest case when we
only keep 1 digit of the error (and round it of course) and round the
value correspondingly. I've been searching around for a simple
function that would take 2 float arguments and would return a string
but didn't find anything although something tells me it's been done a
gazillion times.
What would be the simplest such function?
Cheers,
Daniel
