Looking for a JavaScript regex that can remove any leading 0 in a string if the string is an integer.
0 => ''
0000 => ''
001 => 1
0.11 => 0.11
0000.11 => 0.11
11000 => 11000
I've been attempting to solve this using regex, but haven't succeeded yet.
Here is a potential solution: ^0+(?!\.). You can see an example of how this expression works here.
While Regex was requested, have you considered utilizing the parseFloat function instead?
let value = (parseFloat("0000.11") || '').toString();
The following process works for me:
Locate: ^0+([.1-9])
Substitute with: $1
Hey there Arnold,
Whenever I need to get rid of leading zeros from a number, I rely on the following regular expression:
var str = str.replace(/(^| )(0+)/g, "");
This regex specifically targets any zero characters occurring one or more times at the beginning of a line or after a space.
