Bound Precision
bound_precision(vals)numeric vector of values in the interval [0, 1] to be
bounded within arbitrary machine precision. The most common use of this
functionality is to avoid indeterminate or non-finite values after the
application stats::qlogis.
A numeric vector of the same length as vals, where
 the returned values are bounded to machine precision. This is intended to
 avoid numerical instability issues.
Bound values in the unit interval to machine precision in order to avoid numerical instability issues in downstream computation.
