|Subject:||Wrong value for PI|
This package appears to use an incorrect value for PI. Line 7 of NationalGrid.pm is: use constant PI => 3.141592653897543238452643383279; ***** * I think this should be: use constant PI => 3.141592653589793238462643383279; ***** * This constant is used in the degrees-to-radians conversion functions deg2rad and rad2deg, which results in very slight inaccuracy in these conversions. The inaccuracy is estimated to cause a typical conversion from lat/long to OSGR to be out by a few millimetres, which is insignificant. This bug report is therefore purely academic.
