Test Status Code Input and Output
1   Pass

ans = 1 0 0 1

2   Pass
%% x = [-1 2 3.3 4 -7.54]; y_correct = [true true false true false]; assert(isequal(checkIfinteger(x),y_correct))

3   Pass
%% x = [pi 2.2 single(3.78) -4.34 eps inf] ; y_correct = [false false false false false false]; assert(isequal(checkIfinteger(x),y_correct))

ans = 0 0 0 0 0 0

4   Pass
%% x = [1.0 0 nan -6.0]; % infact nan is 'not a number' y_correct = [true true false true]; assert(isequal(checkIfinteger(x),y_correct))
