| Description: | Generate random numbers from an underlying distribution,
but restricted to a certain interval.
For continuous distributions,
low < random < high
will hold true, i.e., numbers are restricted to the open interval (low, high).
If the distribution itself is restricted to, e.g., positiv numbers, setting
low < 0 will still only return positive numbers. Clipping only excludes numbers
outside (low, high).
For discrete distribtions, numbers are limited to {low, low+1, ... high}, i.e.,
in this case min and max are included.
Numbers are clipped by re-drawing any number outside (low, high), until
a number in (log, high) is drawn. The actual distribution of random
numbers drawn will be a distorted version of the underlying
distribution.

| Parameters: |
/low lower bound (default: -inf)
/high upper bound (default: +inf)
Note:
- Clipped generators can be very inefficient if there is little probability
mass in (low, high).
- For continuous distributions, the probability of actually drawing
min or max is approximately 2^-62 ~ 2e-19, i.e., negligible. Therefore,
one can only clip to open intervals.
- There are also *_clipped_to_boundary versions of the generators. These
return the respective boundary value if a value outside the interval is
drawn. These versions are mainly provided to allow reproduction of
publications that used this strategy.
