Using RegEx how do I remove the trailing zeros from a decimal number

What about stripping the trailing zeros before a \b boundary if there's at least one digit after the .

(\.\d+?)0+\b

And replace with what was captured in the first capture group.

$1

See test at regexr.com

Regex:

^(\d+\.\d*?[1-9])0+$

(\.\d*?[1-9])0+$

Replacement string:

$1

DEMO

Code:

var result:String = theStringOfTheNumber.replace(/(\.\d*?[1-9])0+$/g, "$1" );
