No, that’s just from practical experience with the command as well as what’s been said here about it since 20 years or so.
As far as I know it’s all based on this core function, which as you can see from the API reference does not have a tolerance argument.

In general with these functions, if there is no tolerance argument they use either the built-in “zero tolerance”

or something similar like “square root epsilon”.
