%if true
% code
% end
C = {'long: 151.125#';'long: 151.126#'}
for i=1:length(C)
nn{i}=(C{i}(7:13));
end
A = cell2mat(nn')
B = str2num(A)% array with numbers only

Do NOT use loops or cellfun for this, unless you really want to write complex and slow MATLAB code.
The most efficient solution is to use sscanf like this:
C = {'long: 151.125#';'long: 151.126#'};
V = sscanf([C{:}],'long:%f#')
V = 2×1
151.1250 151.1260

Another possible solution:
C = {'long: 151.125#';'long: 151.126#'};
V = regexp(C,'[?\d.]+','match','once');
V = str2double(V);
>> V
V =
151.1250
151.1260
