I have a list like this :
Ll
$a
3.4 5.6 -2.1 -7.8
$b
2.1 6.7
$c
-6.7,0.001,8.9
I want to find out the maximum number for all elements of the list irrespective of the signs. i.e. I want my out put to look like this :
Ll
$a
-7.8
$b
6.7
$c
8.9
Is there a way to do this through single command line ? Can it be done using the 'by' command?
