> BigFraction(double) constructor does not treat subnormal numbers correctly
> --------------------------------------------------------------------------
>
> Key: NUMBERS-119
> URL: https://issues.apache.org/jira/browse/NUMBERS-119
> Project: Commons Numbers
> Issue Type: Bug
> Components: fraction
> Affects Versions: 1.0
> Reporter: Heinrich Bohne
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h
>
> 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.
