Have you finished self?.rand? My IRB accepts both 0.0 and 0..0.

No I havent, it's one of the remaining functions left. It's really weird.

Implementation details talk aside – what classes beside Integer sastisfies the _Timeout interface, interstingly?
4.5.divmod(1)[1] * 1000000000 #=> 500000000.0

The only valid options are specified in the docs i guess … ? 🤷

| # <!-- | ||
| # rdoc-file=process.c | ||
| # - exec([env,] command... [,options]) | ||
| # --> | ||
| # Replaces the current process by running the given external *command*, which | ||
| # can take one of the following forms: | ||
| # | ||
| # `exec(commandline)` | ||
| # : command line string which is passed to the standard shell | ||
| # `exec(cmdname, arg1, ...)` | ||
| # : command name and one or more arguments (no shell) | ||
| # `exec([cmdname, argv0], arg1, ...)` | ||
| # : command name, `argv[0]` and zero or more arguments (no shell) | ||
| # | ||
| # | ||
| # In the first form, the string is taken as a command line that is subject to | ||
| # shell expansion before being executed. | ||
| # | ||
| # The standard shell always means `"/bin/sh"` on Unix-like systems, otherwise, | ||
| # `ENV["RUBYSHELL"]` or `ENV["COMSPEC"]` on Windows and similar. The command is | ||
| # passed as an argument to the `"-c"` switch to the shell, except in the case of | ||
| # `COMSPEC`. | ||
| # | ||
| # If the string from the first form (`exec("command")`) follows these simple | ||
| # rules: | ||
| # | ||
| # * no meta characters, | ||
| # * not starting with shell reserved word or special built-in, | ||
| # | ||
| # | ||
| # Ruby invokes the command directly without shell. | ||
| # | ||
| # You can force shell invocation by adding ";" to the string (because ";" is a | ||
| # meta character). | ||
| # | ||
| # Note that this behavior is observable by pid obtained (return value of spawn() | ||
| # and IO#pid for IO.popen) is the pid of the invoked command, not shell. | ||
| # | ||
| # In the second form (`exec("command1", "arg1", ...)`), the first is taken as a | ||
| # command name and the rest are passed as parameters to command with no shell | ||
| # expansion. | ||
| # | ||
| # In the third form (`exec(["command", "argv0"], "arg1", ...)`), starting a | ||
| # two-element array at the beginning of the command, the first element is the | ||
| # command to be executed, and the second argument is used as the `argv[0]` | ||
| # value, which may show up in process listings. | ||
| # | ||
| # In order to execute the command, one of the `exec(2)` system calls are used, | ||
| # so the running command may inherit some of the environment of the original | ||
| # program (including open file descriptors). | ||
| # | ||
| # This behavior is modified by the given `env` and `options` parameters. See | ||
| # ::spawn for details. | ||
| # | ||
| # If the command fails to execute (typically Errno::ENOENT when it was not | ||
| # found) a SystemCallError exception is raised. | ||
| # | ||
| # This method modifies process attributes according to given `options` before | ||
| # `exec(2)` system call. See ::spawn for more details about the given `options`. | ||
| # | ||
| # The modified attributes may be retained when `exec(2)` system call fails. | ||
| # | ||
| # For example, hard resource limits are not restorable. | ||
| # | ||
| # Consider to create a child process using ::spawn or Kernel#system if this is | ||
| # not acceptable. | ||
| # | ||
| # exec "echo *" # echoes list of files in current directory | ||
| # # never get here | ||
| # | ||
| # exec "echo", "*" # echoes an asterisk | ||
| # # never get here | ||

The [T] here has no practical effect.

Would conventions use R for Return?
