opaque type BigDecimal

Big BigDecimal

BigDecimal is an opaque value holding java.math.BigDecimal

BigDecimal is used for really large floating point calculations

 // Calculate number Pi using Nilakantha series

 Stream(2.0.Big)
   .unfold(_.last + 4)
   .takeFirst(1000) // the more - the better
   .map(v => (4.0.Big / (v * (v + 1) * (v + 2)) - 4.0.Big / ((v + 2) * (v + 3) * (v + 4))))
   .fold(3.0.Big)(_ + _)
   .tp

 // Prints: 3.1415926535585900763679167025419016466613791096007613231066955478
