Baste Nesse Buanes created MATH-835: ---------------------------------------
Summary: Fraction percentageValue rare overflow Key: MATH-835 URL: https://issues.apache.org/jira/browse/MATH-835 Project: Commons Math Issue Type: Bug Affects Versions: 3.0 Reporter: Baste Nesse Buanes Priority: Minor The percentageValue() method of the Fraction class works by first multiplying the Fraction by 100, then converting the Fraction to a double. This causes overflows when the numerator is greater than Integer.MAX_VALUE/100, even when the value of the fraction is far below this value. The patch changes the method to first convert to a double value, and then multiply this value by 100 - the result should be the same, but with less overflows. An addition to the test is also included. -- This message is automatically generated by JIRA.
