The bounds can be optionally excluded to sample from the open interval
(lower, upper). In this case if the bounds have the same sign the
open interval must contain at least 1 double value between the limits; if the
bounds have opposite signs the open interval must contain at least 2 double values
between the limits excluding -0.0. Thus the interval (-x,x) will
raise an exception when x is Double.MIN_VALUE.

(lower, upper).IllegalArgumentException - If the open interval is invalid.Copyright © 2016–2022 The Apache Software Foundation. All rights reserved.
