javascript - Further Regex sums -

after getting answer aduch:

with regex:      /((-|\+)?([0-9]+|)(\.?[0-9]+))/g  can use array.prototype.reduce sum numbers       var str = 'hello +0.50 world hello 1 world hello -10 world',         re = /((-|\+)?([0-9]+|)(\.?[0-9]+))/g,         sum;      sum = (str.match(re) || []).reduce(function (prev, current) {        if (object.prototype.tostring.call(prev) !== '[object number]') {            prev = parsefloat(prev, 10);        }        return prev + parsefloat(current, 10);     }, 0);      // sum should equal -8.5 here  note `str.match(re)` may return `null`, make sure call `reduce` on array. 

i wondering if possible ignore things in brackets, there.

here example of strings added together:

+0.08 attack damage per level (+1.35 @ champion level 18) 

it current adds in string, yes - did ask for, doesn't add 0.08 , 1.35 itself, merges them together.

i'd either them separate, 1 in brackets , 1 isn't or ignore content within brackets. (content after "level .." within brackets should ignored in cases)

to keep first number maybe try:

^((-|\+)?([0-9]+|)(\.?[0-9]+))

or simpler

^((-|\+)?\d*\.?\d*) 

remember use capture groups if want more 1 matches. http://www.regular-expressions.info/brackets.html
