Like I tried to convey:
some compilers, some operating system services can have a mind of their own.
As soon as a ' or " is encountered, the input or part of the input can be
interpreted as a string with numerical value zero.
As soon as for instance a \ or / or : is encountered, the input or part of
the input can be seen as illegal because some characters are reserved for
file path names.
This behavior could result in:
being interpreted as
Try again with a value that cannot be attributed to rounding, like
If this produces the same result as
Then you know my theory could be true.
Solution: do not use illegal characters in the input.
