Work Description: Schamschi commented on issue #56: NUMBERS-119: Correct
bug in BigFraction(double) constructor
URL: https://github.com/apache/commons-numbers/pull/56#issuecomment-505207901
I just noticed that the coveralls report is lying about the extent of the
decrease in coverage. All the lines in ArithmeticUtils purportedly uncovered by
this pull request are already not covered in the master branch (some of them
even seem to be unreachable).

> 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: 1h
> 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.
