Number with leading zero in JavaScript
(3 answers)
Closed 2 years ago.
Have some doubts about the javascript. when I try to console
a = 021
console.log(a) // 17
why it is changing and how to store the exact value in the variable
Because with leading zero it's a octal-number so 21 is 2*8+1 = 16.
But when you print it out it's in decimal.

I'm confused where I want to split the correspondence_code value like in the image below : let say I want to get just the first 5 digits like 16020 it is possible just getting the first 5 value? Thanks in advance
var result = objt['psgc'].filter(obj => {
return obj.geographic_level === "province"
})
// I want to split the value result -> correspondence_code with only first 5 digits

I currently try my best with the SteamAPI, for that I need the Profile-IDs. I tried out with my own, but somehow js changes the id.
EG:

My ID is 76561198272848927, but JS somehow always change the last two digits from 27 to 30. Why? And how do I fix this?

Javascript leading 0 on integers getting wrong value on console.log.
Why I am getting like this ?
Code:
console.log(456);
console.log(0456);
Output:
456
302
Because JS "translates" 0456 as an octal value, since it has a trailing zero and all its digits < 8.

I want to declare
var a = 0213;
document.write(a);
but it not work .when console.log(a); variable
different.
Numbers with a leading 0 are interpreted as octal (base 8).
Octal 0213 == decimal 139.
If you need the value 213 (decimal), leave off the leading 0.

Is this a failure in JavaScript's attempt to convert them to numbers? If so, what numbers are they being converted to? Or what is the logic behind the string 10 being less than the string 9?
It's comparing the strings "alphabetically", and 1 comes before 9 in the character "alphabet".
