[x3d-public] Ran into an interesting diff, X3DJSAIL JavaScript development, trailing 0s issue again.

Excellent catch, as your excerpts show it was not handling exponents for scientific notation properly.  Now fixed.

Incidentally these functions are exposed for X3DJSAIL programmer use.  I refactored them to be even more convenient, either providing a current value or else (via static method) converting any other value.

======================
Class org.web3d.x3d.jsail.fields.SFFloatObject
	public java.lang.String stripTrailingZeroes()
	public static java.lang.String stripTrailingZeroes(float value)
http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/fields/SFFloat.html#stripTrailingZeroes--
http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/fields/SFFloat.html#stripTrailingZeroes-float-

Class org.web3d.x3d.jsail.fields.SFDoubleObject
	public java.lang.String stripTrailingZeroes()
	public static java.lang.String stripTrailingZeroes(double value)
http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/fields/SFDouble.html#stripTrailingZeroes--
http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/fields/SFDouble.html#stripTrailingZeroes-double-

Utility method to strip trailing fractional zeroes from double value First converting an integer (such as 100) to String results in trailing decimal point and zero (such as 100.0) which then allows rest of regex filter to work.
======================

Fixed and deployed, hope your next tests run clean on this one!
