Document

Returns a representation of the specified floating-point value according to the IEEE 754 floating-point "double format" bit layout.

Usage

From source file:MutableDouble.java

/**
 * Compares this object against the specified object. The result is
 * <code>true</code> if and only if the argument is not <code>null</code>
 * and is a <code>Double</code> object that represents a double that has the
 * identical bit pattern to the bit pattern of the double represented by this
 * object. For this purpose, two <code>double</code> values are considered
 * to be the same if and only if the method
 * {@link Double#doubleToLongBits(double)}returns the same long value when
 * applied to each.//  w w  w  .  j  a  v  a  2  s  .c o m
 * <p>
 * Note that in most cases, for two instances of class <code>Double</code>,<code>d1</code>
 * and <code>d2</code>, the value of <code>d1.equals(d2)</code> is
 * <code>true</code> if and only if <blockquote>
 * 
 * <pre>
 * d1.doubleValue() == d2.doubleValue()
 * </pre>
 * 
 * </blockquote>
 * <p>
 * also has the value <code>true</code>. However, there are two exceptions:
 * <ul>
 * <li>If <code>d1</code> and <code>d2</code> both represent
 * <code>Double.NaN</code>, then the <code>equals</code> method returns
 * <code>true</code>, even though <code>Double.NaN==Double.NaN</code> has
 * the value <code>false</code>.
 * <li>If <code>d1</code> represents <code>+0.0</code> while
 * <code>d2</code> represents <code>-0.0</code>, or vice versa, the
 * <code>equal</code> test has the value <code>false</code>, even though
 * <code>+0.0==-0.0</code> has the value <code>true</code>. This allows
 * hashtables to operate properly.
 * </ul>
 * 
 * @param obj
 *          the object to compare with.
 * @return <code>true</code> if the objects are the same; <code>false</code>
 *         otherwise.
