For me there is a relationship between these two systems. It is necessary to do another search to find it and thus to eliminate this miscalculation.\\ {{{ $ ocaml OCaml version 4.04.0 # 16.0/.0.2;; - : float = 80. # 16.0/.0.02;; - : float = 800. # 16.0/.0.002;; - : float = 8000. # 16.0/.0.0002;; - : float = 80000. # 16.0/.0.00002;; - : float = 799999.99999999988 # 16.0/.0.000002;; - : float = 8000000. # 16.0/.0.0000002;; - : float = 80000000. # 16.0/.0.00000002;; - : float = 800000000. # 16.0/.0.000000002;; - : float = 7999999999.999999 # 16.0/.0.0000000002;; - : float = 80000000000. # 16.0/.0.00000000002;; - : float = 800000000000. # 16.0/.0.000000000002;; - : float = 8e+012 # 16.0/.0.0000000000002;; - : float = 8e+013 # 16.0/.0.00000000000002;; - : float = 8e+014 # 16.0/.0.000000000000002;; - : float = 7999999999999999. # 16.0/.0.0000000000000002;; - : float = 8e+016 # 16.0/.0.00000000000000002;; - : float = 8e+017 # 16.0/.0.000000000000000002;; - : float = 7.999999999999999e+018 # 16.0/.0.0000000000000000002;; - : float = 8e+019 # 16.0/.0.00000000000000000002;; - : float = 8e+020 # }}} Today I decided to close this ticket as invalid because I do not know what else to choose to close this ticket.
