[jira] [Created] (MATH-1256) Interval class upper and lower check
Gunel Jahangirova created MATH-1256:
---------------------------------------
Summary: Interval class upper and lower check
Key: MATH-1256
URL: https://issues.apache.org/jira/browse/MATH-1256
Project: Commons Math
Issue Type: Bug
Reporter: Gunel Jahangirova
Priority: Minor
In class Interval, which is in the package org.apache.commons.math4.geometry.euclidean.oned it is possible to pass the value for variable upper less than the value of variable lower, which is logically incorrect and also causes the method getSize() to return negative value.
For example:
@Test
public void test1() throws Throwable {
Interval interval0 = new Interval(0.0, (-1.0));
double double0 = interval0.getSize();
assertEquals((-1.0), double0, 0.01D);
}
