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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
