Problem identifying a symbolic variable as a double

Hello!
I’m dealing with symbolic toolbox in Matlab. I have this code:
>> syms a b c;
a = b + c;
>> res = subs(a, {b, c}, {1, 1})
res =
2
>> isnumeric(res)
ans =
0
I would like an “isnumeric” function that returns 1 for this situation. I tried vpa and double but the answer is still 0. There is any other function that I can use or should I write it by myself?
Thanks!

Dina, did you try
isnumeric(double(res))
Just in case this does not result in a "1", what MATLAB release are you working with?
