GeodeticCalculator - Wrong azimuth calculation
----------------------------------------------

                 Key: GEOT-2715
                 URL: http://jira.codehaus.org/browse/GEOT-2715
             Project: GeoTools
          Issue Type: Bug
          Components: core referencing
    Affects Versions: 2.4.5
         Environment: winxp, java 1.5.0_11
            Reporter: Katrin Lasinger
         Attachments: GeodeticCalculatorTest.java

When trying to compute a geodetic curve at the equator from east to west,
a wrong azimuth is calculated.

The problem seems to be in the (private) method "computeDirection":
If "dlon" (delta longitude) is < 0 a wrong calculation is done:
 ... Math.PI * (3 / 2) ...
(3 / 2) is computed as integer and then used with pi.

The whole computation must be performed with double precision!
