我目前正在研究真实世界的 Ocaml，但我在运行sum.ml的 OCaml“corebuild”编译版本时遇到了困难：

$ ./sum.native 
1
2
3

Uncaught exception:

  (Invalid_argument "Float.of_string ")

Raised at file "pervasives.ml", line 31, characters 25-45
Called from file "sum.ml", line 7, characters 44-61
Called from file "sum.ml", line 10, characters 24-46

我究竟做错了什么？

谢谢你！
