All Implemented Interfaces:

SFDouble, X3DField
```
public class SFDoubleObject
extends X3DConcreteField
implements SFDouble
```
This utility class provides a concrete implementation corresponding to SFDouble X3D field type.

Package hint: This specification class is defined by the X3D Java Language Binding Specification for the Scene Authoring Interface (SAI). SFDouble is a double-precision floating-point type. Array values are optionally separated by commas. See GeoVRML 1.0 Recommended Practice, Section 2.3, Limitations of Single Precision for rationale.

  - stripTrailingZeroes
```
public static java.lang.String stripTrailingZeroes(double value)
```
    Utility method to always strip trailing fractional zeroes from String value of any given double. Applicability: first converting an integer (such as 100) to double and then String results in trailing decimal point and zero (such as 100.0).

    Parameters:
    
    newValue - The newValue to apply
    
    Returns:
