+/**
+ * The {@code Character} class wraps a value of the primitive
+ * type {@code char} in an object. An object of type
+ * {@code Character} contains a single field whose type is
+ * {@code char}.
+ * <p>
+ * In addition, this class provides several methods for determining
+ * a character's category (lowercase letter, digit, etc.) and for converting
+ * characters from uppercase to lowercase and vice versa.
+ * <p>
+ * Character information is based on the Unicode Standard, version 6.0.0.
+ * <p>
+ * The methods and data of class {@code Character} are defined by
+ * the information in the <i>UnicodeData</i> file that is part of the
+ * Unicode Character Database maintained by the Unicode
+ * Consortium. This file specifies various properties including name
+ * and general category for every defined Unicode code point or
+ * character range.
+ * <p>
+ * The file and its description are available from the Unicode Consortium at:
+ * <ul>
+ * <li><a href="http://www.unicode.org">http://www.unicode.org</a>
+ * </ul>
+ *
+ * <h4><a name="unicode">Unicode Character Representations</a></h4>
+ *
+ * <p>The {@code char} data type (and therefore the value that a
+ * {@code Character} object encapsulates) are based on the
+ * original Unicode specification, which defined characters as
+ * fixed-width 16-bit entities. The Unicode Standard has since been
+ * changed to allow for characters whose representation requires more
+ * than 16 bits.  The range of legal <em>code point</em>s is now
+ * U+0000 to U+10FFFF, known as <em>Unicode scalar value</em>.
+ * (Refer to the <a
+ * href="http://www.unicode.org/reports/tr27/#notation"><i>
+ * definition</i></a> of the U+<i>n</i> notation in the Unicode
+ * Standard.)
+ *
+ * <p><a name="BMP">The set of characters from U+0000 to U+FFFF is
+ * sometimes referred to as the <em>Basic Multilingual Plane (BMP)</em>.
+ * <a name="supplementary">Characters</a> whose code points are greater
+ * than U+FFFF are called <em>supplementary character</em>s.  The Java
+ * platform uses the UTF-16 representation in {@code char} arrays and
+ * in the {@code String} and {@code StringBuffer} classes. In
+ * this representation, supplementary characters are represented as a pair
+ * of {@code char} values, the first from the <em>high-surrogates</em>
+ * range, (&#92;uD800-&#92;uDBFF), the second from the
+ * <em>low-surrogates</em> range (&#92;uDC00-&#92;uDFFF).
+ *
+ * <p>A {@code char} value, therefore, represents Basic
+ * Multilingual Plane (BMP) code points, including the surrogate
+ * code points, or code units of the UTF-16 encoding. An
+ * {@code int} value represents all Unicode code points,
+ * including supplementary code points. The lower (least significant)
+ * 21 bits of {@code int} are used to represent Unicode code
+ * points and the upper (most significant) 11 bits must be zero.
+ * Unless otherwise specified, the behavior with respect to
+ * supplementary characters and surrogate {@code char} values is
+ * as follows:
+ *
+ * <ul>
+ * <li>The methods that only accept a {@code char} value cannot support
+ * supplementary characters. They treat {@code char} values from the
+ * surrogate ranges as undefined characters. For example,
+ * {@code Character.isLetter('\u005CuD840')} returns {@code false}, even though
+ * this specific value if followed by any low-surrogate value in a string
+ * would represent a letter.
+ *
+ * <li>The methods that accept an {@code int} value support all
+ * Unicode characters, including supplementary characters. For
+ * example, {@code Character.isLetter(0x2F81A)} returns
+ * {@code true} because the code point value represents a letter
+ * (a CJK ideograph).
+ * </ul>
+ *
+ * <p>In the Java SE API documentation, <em>Unicode code point</em> is
+ * used for character values in the range between U+0000 and U+10FFFF,
+ * and <em>Unicode code unit</em> is used for 16-bit
+ * {@code char} values that are code units of the <em>UTF-16</em>
+ * encoding. For more information on Unicode terminology, refer to the
+ * <a href="http://www.unicode.org/glossary/">Unicode Glossary</a>.

+     * by {@code float} to {@code double}, is <em>not</em>
+     * equivalent to converting a string directly to

+     * value {@code 0.10000000149011612}; the {@code float}
+     * literal {@code 0.1f} represents a different numerical

+     * followed by {@code double} to {@code float}, is

+/**
+ * The class {@code Math} contains methods for performing basic
+ * numeric operations such as the elementary exponential, logarithm,
+ * square root, and trigonometric functions.
+ *
+ * <p>Unlike some of the numeric methods of class
+ * {@code StrictMath}, all implementations of the equivalent
+ * functions of class {@code Math} are not defined to return the
+ * bit-for-bit same results.  This relaxation permits
+ * better-performing implementations where strict reproducibility is
+ * not required.
+ *
+ * <p>By default many of the {@code Math} methods simply call
+ * the equivalent method in {@code StrictMath} for their
+ * implementation.  Code generators are encouraged to use
+ * platform-specific native libraries or microprocessor instructions,
+ * where available, to provide higher-performance implementations of
+ * {@code Math} methods.  Such higher-performance
+ * implementations still must conform to the specification for
+ * {@code Math}.
+ *
+ * <p>The quality of implementation specifications concern two
+ * properties, accuracy of the returned result and monotonicity of the
+ * method.  Accuracy of the floating-point {@code Math} methods
+ * is measured in terms of <i>ulps</i>, units in the last place.  For
+ * a given floating-point format, an ulp of a specific real number
+ * value is the distance between the two floating-point values
+ * bracketing that numerical value.  When discussing the accuracy of a
+ * method as a whole rather than at a specific argument, the number of
+ * ulps cited is for the worst-case error at any argument.  If a
+ * method always has an error less than 0.5 ulps, the method always
+ * returns the floating-point number nearest the exact result; such a
+ * method is <i>correctly rounded</i>.  A correctly rounded method is
+ * generally the best a floating-point approximation can be; however,
+ * it is impractical for many floating-point methods to be correctly
+ * rounded.  Instead, for the {@code Math} class, a larger error
+ * bound of 1 or 2 ulps is allowed for certain methods.  Informally,
+ * with a 1 ulp error bound, when the exact result is a representable
+ * number, the exact result should be returned as the computed result;
+ * otherwise, either of the two floating-point values which bracket
+ * the exact result may be returned.  For exact results large in
+ * magnitude, one of the endpoints of the bracket may be infinite.
+ * Besides accuracy at individual arguments, maintaining proper
+ * relations between the method at different arguments is also
+ * important.  Therefore, most methods with more than 0.5 ulp errors
+ * are required to be <i>semi-monotonic</i>: whenever the mathematical
+ * function is non-decreasing, so is the floating-point approximation,
+ * likewise, whenever the mathematical function is non-increasing, so
+ * is the floating-point approximation.  Not all approximations that
+ * have 1 ulp accuracy will automatically meet the monotonicity
+ * requirements.
