I have a json file which I am accessing through JS
latitude =data8.weblandmarks8[j].latitude + latitude;
should add all the latitudes so that I could average them later instead it just concatenates them How should i achieve what I want to
Json entry
"latitude": "28.14331",
Aside from using parseFloat you could convert to Number, it's slightly faster and usable for both integers and floats1:
latitude = Number(data8.weblandmarks8[j].latitude) + latitude;
1 another advantage for integers is that you don't need to supply a radix. Number('09') returns 9, whereas parseInt('09') (i.e. parseInt without a radix) returns 0 (that's because parseInt defaults to an octal - radix 8).
Convert it to a number: You'll use the parseFloat() or parseInt() methods.
parseFloat('28.14331') // 28.14331
parseInt('28.14331', 10) // 28
radix always of base 10 if you use parseIntyou can use the parseFloat function to turn the string into a number
latitude = parseFloat(data8.weblandmarks8[j].latitude) + latitude;
