MATLAB: How to add one digit to another digits

addingcalculationdigitformat

For example, I have a number b=5; and i need to add it by another digits, for example 1234 and get the answer 12345. Code may show like: set(handles.text1,'string',1234+b) An error is "1234+b" and i don't know how format it that one digit adds to another digits. Thanks in advance.

strcat('1234','5')

you can convert any number to string with num2str or other similar function

strcat('1234',num2str(5))

b=5;

strcat('1234',num2str(b))

num2str(uint64(14472334024676221),'%u')

You have exceeded flintmax:

flintmax Largest consecutive integer in floating point format.
  flintmax returns the largest consecutive integer in IEEE double
  precision, which is 2^53. Above this value, double precision format
  does not have integer precision, and not all integers can be represented 
  exactly.

MATLAB: Matching digits

A=1234; B=1248; C =1238;
Astr = num2str(A);  %you'll need this one 3x so convert it once.
idxstop = find(any(bsxfun(@ne,vertcat(Astr,num2str(B),num2str(C)),Astr),1),1,'first');
common = Astr(1:idxstop-1)
