    Runing the following in Scala 2.9.1 or more recent: BigDecimal("23953295732957329573295379352353252353253") % BigDecimal(math.Pi) results in: java.lang.ArithmeticException: Division impossible at java.math.BigDecimal.divideToIntegralValue( at java.math.BigDecimal.divideAndRemainder( at java.math.BigDecimal.remainder( at scala.math.BigDecimal.remainder(BigDecimal.scala:256) at scala.math.BigDecimal.$percent(BigDecimal.scala:260) at .<init>(<console>:8) at .<clinit>(<console>) at .<init>(<console>:11) at .<clinit>(<console>) at $print(<console>) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke( at sun.reflect.DelegatingMethodAccessorImpl.invoke( at java.lang.reflect.Method.invoke( at$ at$Request$$anonfun$14.apply(IMain.scala:920) at$$anonfun$1.apply$mcV$sp(Line.scala:43) at$$anon$ at Whereas in 2.8 you get: res0: scala.math.BigDecimal = 0.513676093799207 This has to do with the addition of the MathContext object. That object was added to limit decimal expansion of, e.g. BigDecimal(1) / BigDecimal(3), but introduces problems for the remainder operation.
