You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: testEvalFunc.m
    path of file: ./repos/d2d/arFramework3/ThirdParty/EvA2/JEInterface/@JEInterface
    
    the code of the file until where you have to start completion: function testEvalFunc(int) 
% Test the fitness function output format.
wordwidth=32;

if (strcmp(int.dataType,eva2.server.go.problems.MatlabProblemDataTypeEnum.typeBinary))
    % binary problem
    s=sprintf('Binary problem of bitwidth %d', int.dim);
    disp(s);
    %numInts=ceil(int.dim/wordwidth);
    % generate trial vector
    %x=ceil(rand(1,numInts).*(2^wordwidth));
    %overheadBits=numInts*wordwidth-int.dim;
    %x(numInts)=bitshift(x(numInts),-overheadBits); % shift right by overhead
    bs=eva2.tools.math.RNG.randomBitSet(0.5, int.dim);
    x=convertUnsignedJE(int, bs);
