theorem INTTOREAL:
  for M being Matrix of INT.Ring
  holds M is Matrix of F_Real
  proof
    let M be Matrix of INT.Ring;
    (the carrier of INT.Ring)* c= (the carrier of F_Real)*
    by NUMBERS:15,FINSEQ_1:62;
    then rng M c= (the carrier of F_Real)*;
    hence thesis by FINSEQ_1:def 4;
  end;
