There's a total lack of evidence for that. Furthermore,

1. Roundoff error is not of a fixed magnitude.

2. A user may choose to ignore roundoff errors, but that is not the prerogative 
of the language.

3. What is an acceptable amount of roundoff error is not decidable by the language.

4. At Boeing doing design work, I've seen what happens when engineers ignore 
roundoff errors. It ain't pretty. It ain't safe. It ain't correct.
