User file must have the same bytes with std file.
The two byte streams must be exactly the same.
There is no "PE" in this mode.
Compare two streams of float numbers which are splitted by ascii whitespaces.
Parse any float number as f64 (aka double in C language).
Ascii whitespaces between two float numbers are considered as a single separator symbol.
Use CLI option --eps to specify eps value, for example --eps 1e-3.
There is no "PE" in this mode.
