I have this array and it is formatted as string:
['6.35', '2.72', '11.79', '183.25']
The problem is that when I convert it to numbers (using - without double quotes )
array.match(/\d+/g).map(Number) || 0;
it changes the dots used for decimals to commas. Then I end up with this new array:
6,35,2,72,11,79,183,25
So, instead of having 4 items inside the array, now I have 8 items, as my delimiters are commas.
Any ideas of how I can convert this array without replacing the dots?
Assuming you have an array in a string format, you can use the following regex to match all the decimals and then use .map(Number)
const str = "['6.35', '2.72', '11.79', '183.25']",
array = str.match(/\d+(?:\.\d+)?/g).map(Number)
console.log(array)
-? at the beginning of the regex: /-?\d+(?:\.\d+)?/\d matches only digits, it's the short for [0-9]. For example, in 6.35 \d+ matches 6 and then 35 separately and the dot is ignored. What you get in result is array containing those matches.
As suggested in other answers, use of match is redundant in your case and you can go with:
array.map(Number)
You could just map numbers.
var array = ['6.35', '2.72', '11.79', '183.25'],
numbers = array.map(Number);
console.log(numbers);
Map over the array with the Number function, it will handle the conversion:
console.log(['6.35', '2.72', '11.79', '183.25'].map(Number));If you want commas in your numbers, then you must stick with a string representation.
See this SO answer about a similar problem with ChartJS.
var num = ['6.35', '2.72', '11.79', '183.25'].map(num => Number(num));
console.log(num);Parse the values to float :
console.log(['6.35', '2.72', '11.79', '183.25'].map(i => parseFloat(i)));If for some reason .map() doesn't work just use a loop :
var array = ['6.35', '2.72', '11.79', '183.25']
var x = 0;
var len = array.length
while(x < len){
array[x] = parseFloat(array[x]);
x++
}
console.log(array)
var arr = ["6,35,2,72,11,79,183,25"]
var result=arr.map(Number);
result[]
typeof(result[])
I was having the same problem this is a solution i found i had
x = "11,1.1,100,100,2,3333,99"
and i wanted
x = [11,1.1,100,100,2,3333,99]
here's my solution
x.toString().replace(/, +/g, ",").split(",").map(Number)
