I have a file which has lines like this.
area : 37.24;
power : 1.28, 2.73, 3.84;
I need to substitute each number with it's double (number*2).
Is there anyway I can do this in VIM?
I don't have perldo command in my version of VIM.
%s/[0-9.]\+/\=2.0*str2float(submatch(0))/g
-from-
[0-9.]\+ one or more digits or periods
-to-
\= ... evaluate following expression
2.0 ... obvious
* ... also obvious
str2float(submatch(0)) take entire match and convert that string to a float
/g ... as many matches as possible per line
HTH,
