Looking for a regular expression that can extract only numbers from a string. Specifically, numbers not preceded by a character. For example: "(a/(b1/8))*100 In this case, we do not want to include b1. We are interested in retrieving numbers like 8, 100, etc.
To match specific word boundaries, such as those described in the regular-expressions.info website, you can use the following expression:
\b\d{3}
(?<![a-zA-Z])\d+ is the correct way to go
Using a regular expression, you can extract numbers from a string, keeping only those without a leading character:
let inputString = "(a/(b1/8))*100";
let numbersArray = [];
let match;
const regex = /([a-z]?)(\d+)/g;
while (match = regex.exec(inputString)) {
if (!match[1].length) numbersArray.push(match[2]);
}
alert(numbersArray);
Output:
8, 100

looking for numeric values
^(\d ? \d* : (\-?\d+))\d*(\.?\d+:\d*) $
this pattern will validate any numeric input such as -1.4 , 1.3 , 100 , -100
I have tested this for a custom numeric validation attribute in ASP.NET
