That was a wrong claim... try this on command line...
echo +2345 | grep -E '^(\+|-)?[0-9]+$'

I hope you understood what '^(\+|-)?[0-9]+$' means...

Since you seem concerned with selective and intelligent matches, I would suggest you to go through some good book on regular expressions...

here is one worth it's bucks...

NAME
Ns_AbsoluteUrl, Ns_ParseUrl, Ns_RelativeUrl, Ns_SkipUrl - URL manipulation routines SYNOPSIS
#include "ns.h" int Ns_AbsoluteUrl(Ns_DString *pds, char *url, char *baseurl) int Ns_ParseUrl(char *url, char **pprotocol, char **phost, char **pport, char **ppath, char **ptail) char * Ns_RelativeUrl(char *url, char *location) char * Ns_SkipUrl(Ns_Request *request, int n) _________________________________________________________________ DESCRIPTION
Ns_AbsoluteUrl(pds, url, baseurl) Construct an URL based on baseurl but with as many parts of the incomplete url as possible. Return NS_OK or NS_ERROR. Ns_ParseUrl(url, pprotocol, phost, pport, ppath, ptail) Parse a URL into its component parts. Pointers to the protocol, host, port, path, and "tail" (last path element) will be set by ref- erence in the passed-in pointers. The passed-in url will be modified. Ns_RelativeUrl(url, location) If the url passed in is for this server, then the initial part of the URL is stripped off. e.g., on a server whose location is http://www.foo.com, Ns_RelativeUrl of "http://www.foo.com/hello" will return "/hello". Returns a pointer to the beginning of the relative url in the passed-in url, or NULL if error. Will set errno on error. Ns_SkipUrl(request, n) Return a pointer n elements into the request's url.
