A far cleaner solution:

    console.log(process.argv.slice(2).reduce(function(a, x) {
      return a + parseFloat(x) 
    }, 0));

Why is that cleaner? A for-loop is one of the basic programming constructs.

A for-loop might be a basic programming construct, but it shouldn't be. Mutation and a control flow construct makes for a much worse outlook to the problem than does recursive application of a function.

reduce is one very fundamental construct too https://www.google.com/search?q=universality+of+reduce

Least bytes?

  var a=process.argv,i=a.length,x=0;while(i>2)x-=-a[--i];console.log(x)
