Luc Maisonobe commented on MATH-307:
------------------------------------
I have added rounding mode and scale fields in BigDecimal in subversion tree as
of r894107.
Could you please check if this solves the issue for you ?
> BigReal/Fieldelement divide without setting a proper scale -> exception: no
> exact representable decimal result

> BigReal implements the methode divide of Fieldelement. The problem is that
> there is no scale defined for the BigDecimal so the class will throw an error
> when the outcome is not a representable decimal result.
> (Exception: no exact representable decimal result)
> The workaround for me was to copy the BigReal and set the scale and
> roundingMode the same as version 1.2.
> Maybe is it possible to set the scale in FieldMatrix and implements it also a
> divide(BigReal b, int scale, int roundMode) ??
