Answer 1

The sign should be optional (?), and then you can match a set of numbers followed by a . or a ,, followed by another set of numbers, and replace that match. That way you can match both positive and negative numbers with the same expression.

var string = "Test Alpha 0 -0.25 12,31 31 -123.45 (1-3)"
string = string.replace(/( -?\d+([.,]\d+)?)/g, '');
console.log(string);

Answer 2

You need add the "-" in the regrex condition.

var string = "Test Alpha -0.25 (1-3)"
string = string.replace(/\s*-\d+[.,]\d+/g, "");
console.log(string);

Answer 3

Change the regex statement to match the -, this can be like so:

/\s*-\d+[.,]\d+/g
