Hi.
Cf. issue reported in
https://issues.apache.org/jira/browse/MATH-1256
Quoting the OP:
---
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
---
Is it ever necessary to allow negative intervals (e.g. wrt to
"tolerance")?
If not, I propose to add a check in the constructor:
---CUT---
if (upper < lower) {
throw new
NumberIsTooSmallException(LocalizedFormats.ENDPOINTS_NOT_AN_INTERVAL,
upper, lower, true);
}
---CUT---
OK?
Regards,
Gilles
