Number manipulation within Vim -

April 15, 2015

If I have a data file containing columns of numbers such as

  3.14 0.42 6.66 < / Code>

  Is there any way from within Vim that I can manipulate these tasks like addition, subtraction and division? For example, say that I wanted to add 2.1 to each number in the column, how would I have to go about this? A 
  I can do this by piping for awk, but I would like to know that there is a built-in method, and I have not got anything in help files.

  
  Experiment with expression register  = . 
  The following command will add a number to a number on a line: 
   C & lt; CTRL-R & gt; = & Lt; CTRL-R & gt; "+2.1

Serial.io.setuperoutput (str, systemtext.edcoding.aspx); ScriptScope scope = engine.CreateScope (); ScriptSource src = engine.CreateScriptSourceFromString (testCode); Src.Execute (scope); Sorry for the silly question, it has come to know that there is a path used by IronPathon inside me.       The C # code was not correct. I ...

    Have you ever tried importing Classic C ++ / project into Qt Creator?   Say that I wanted to use some libraries in my GUI project, which must be created. how can I do this?
