--------------------------------

bq. reduce() method obsolete anyway, which could be the target of a new JIRA 
ticket.

>          Issue Type: Bug
>          Components: fraction
>    Affects Versions: 1.0

> The constructor {{BigFraction(double)}} does not take into account the fact 
> that, when the biased exponent of a {{double}} value is {{0}} and the 
> mantissa is not {{0}} (i.e. when the value represents a subnormal number), 
> the actual exponent in effect is not {{-1023}} but {{-1022}} (or, in other 
> words, the effective exponent bias is not {{1023}} but {{1022}}).
> The value of the created {{BigFraction}} is therefore not equal to the value 
> of the passed {{double}} argument.
