select oprator issue(working correctly for positive numbers) negative numbers giving wrong result

[bpradeep508]

a= -29 b= 0 c=select(a>b,a,b); c=-29 c=select(a<b,a,b); c=0

Are a and b signed integers?

[bpradeep508]

encrypt.cxx int main(int argc, char* argv[]) { if (argc < 3) { cerr << "Usage: " << argv[0] << " " << endl; exit(-1); }

/ get input values / int a_val = -29; int b_val = 0;

/ Only tfhe bit executor is needed for encryption/decryption and IO operations / CiContext::set_bit_exec(make_shared("tfhe.sk", TfheBitExec::Secret));

CiInt a{a_val, 16, false}; CiInt b{b_val, 16, false};

a.encrypt().write("a"); b.encrypt().write("b");

} hello.cxx

CiInt a{0, 16, false}; // create from unsigned 8-bit template CiInt b{0, 16, false}; // manually specify value, size and signedness CiInt c{0, 16, false}; // automatically determine size and signedness from value CiInt shift{0,16,false}; CiInt temp{0, 16, false}; a.read("a"); b.read("b"); shift.read("shift"); //temp=(shift<<15)*b; // c = a-temp; //CiBit r=a>b; c = select(a<b,a,b);

c.write("c");

You do a comparison between unsigned values and in this case -29 is bigger than 0.

[bpradeep508]

can you give both positive and negative examples in select
