 You can run specific tests rather than all of them by giving their names
 (without .rs extension) as command line parameters.

 exit code that's not 0, the test fails.
 The output on stdout is treated as (f64, f32, decimal) record, encoded thusly:
 
-- The first eight bytes are a binary64 (native endianness).
-- The following four bytes are a binary32 (native endianness).
-- Then the corresponding string input follows, in ASCII (no newline).

 Incomplete records are an error. Not-a-Number bit patterns are invalid too.
