Heinrich Bohne created NUMBERS-119:
--------------------------------------
Summary: 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
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.
