function res = isint(in)
% ISINT  True for integers.
%   ISINT(IN) returns 1 for those elements that are integers,
%   and 0 otherwise.  Valid for numbers in [-2147483648, 2147483647].
%   Mainly used for input checking in functions.
%
%   To test if any/all element of an array is an integer, use any or all:
%     if(any(isint(1:4))) disp('at least one element is an integer'); end;
%     if(all(isint(1:4))) disp('all elements are integers'); end;
%
%   Example:
%     a = [1 2 3 4 5.5 8.34];
%     isint(a)%  returns [1 1 1 1 0 0]
