Unfortunately not.
"isanumber" is mis-named. It really acts as "isapositivenumber".
The reason is that the tokensiser places the - sign into its
own separate token.  So isanumber(c_token) sees only the '-' sign,
no number.

This has annoyed me many times, but never sufficiently to
replace isanumber() with something better.
