`sample` of `Sketch` returns boundary values occasionally

[xxxnell]

sample of Sketch returns boundary values (e.g. List(..., -1.3346329812349141E307, 7.927339694866348E307, ..., 4.2420349412446703E307, ..., -1.1082857601763558E308...)).

For Sketch about Std with 100 samples, A samples function returns a list containing more than 10% of values greater than 10.

How to get this issue. I was trying like this and see it fine.

scala> import flip.implicits._
import flip.implicits._

scala> val underlying = NumericDist.normal(0.0, 1.0)
underlying: flip.pdf.NormalDist[Double] = NormalDistImpl(Measure,flip.conf.DefaultSmoothDistConf$@3c28372d,0.0,1.0,IRngImpl(1072693248))

scala> val (_, samples) = underlying.samples(100)
samples: List[Double] = List(1.5518866496219879, 1.1936023725606515, 0.38080892362529634, -0.1897430357097696, -1.2207970250688067, 0.3486939321155784, 0.29946337913768784, -1.4227208457792881, -0.3944399185780814, -0.424529776725254, 1.2594303581908546, -2.0007737988860717, 0.9260040590622992, 0.5999675344005262, -0.5033634219485902, -1.5636470479025906, -0.5154388439192938, 0.4027120196305333, -0.5281069068747963, 0.7766441736329389, 0.6110166324257643, -0.37067176833033233, -0.9409052800937043, -0.13015739314390917, 0.2629238869734297, 0.6841060012654049, 0.7111724688446545, 2.176873911486755, -0.09522236721506186, 0.21478528742759107, 0.41557787591997564, 1.2754810779776178, -1.9164464400322176, 0.45128971299902565, 0.10765526607948277, -2.168858107407589, ...

@hyesubba Thank you for your feedback. I admit that the title of this issue can be misleading. This problem occurs occasionally, so a few values generated from samples can be boundary values. So, I changed the title. Also, this problem is only related to Sketch. Unlike sample of Sketch, sample and samples of NumericDist works properly as you said.
