![]() ![]() Returns: a string representation of the argument. Parameters: d - the double to be converted. ![]() To create localized string representations of a floating-point Significant bit of the significand of d must be 0. To x, then d must be one of them and the least To x or if two double values are equally close Representation produced by this method for a finite nonzero argumentĭ. X is the exact mathematical value represented by the decimal The fractional part, and beyond that as many, but only as many, moreĭigits as are needed to uniquely distinguish the argument value fromĪdjacent values of type double. M or a? There must be at least one digit to represent How many digits must be printed for the fractional part of Produced by the method Integer.toString(int). Representing the fractional part of a, followed by theīy a representation of n as a decimal integer, as Magnitude is then represented as the integer part of a,Īs a single decimal digit, followed by '. "computerized scientific notation." Let n be the unique If m is less than 10 -3 or greater than orĮqual to 10 7, then it is represented in so-called.More decimal digits representing the fractional part of m. M, in decimal form with no leading zeroes, followed by Than 10 7, then it is represented as the integer part of If m is greater than or equal to 10 -3 but less."-0.0" and positive zero produces the result "0.0" thus, negative zero produces the result If m is zero, it is represented by the characters."Infinity" and negative infinity produces the result "Infinity" thus, positive infinity produces the result If m is infinity, it is represented by the characters.( '\u002D') if the sign is positive, no sign characterĪppears in the result. The first character of the result is ' -' Magnitude (absolute value) of the argument. Otherwise, the result is a string that represents the sign and.If the argument is NaN, the result is the string.All characters mentioned below are ASCII characters. Returns a string representation of the doubleĪrgument. The sign of a zero inputĪlso has a non-substitutable effect on the result of some mathįor ordered comparisons using the built-in comparison operators Most commonly determines the sign of a zero result, because ofĭividing by zero, +0.0 and -0.0 may not be Positive infinity and negative infinity are neither equal to each ForĮxample, 1.0/+0.0 evaluates to positive infinity whileġ.0/-0.0 evaluates to negative infinity and Represents -0.0, or vice versa, then v1 = v2 hasĪre distinguishable under various floating-point operations. Relation is not satisfied by the = operator. Therefore, for two NaNĪrguments the reflexive property of an equivalence ![]() Properties of an equivalence relation are not satisfied by = operator were deliberately designed to meet other needs Despite notĭefining an equivalence relation, the semantics of the IEEE 754 Notably, the built-in = operation on floating-point In particular, in a numericĮxpression equivalent values can be substituted for oneĪnother without changing the result of the expression, meaningĬhanging the equivalence class of the result of the expression. Least for some purposes, all the members of an equivalence classĪre substitutable for each other. An equivalence class may contain only a single member. Members of the equivalence class are equal to each other under the Operates over into sets called equivalence classes. An equivalence relation partitions the values it For more discussion of equivalence relations and object Relation on pairs of values that is reflexive, symmetric, and Signed zeros ( +0.0 and -0.0), signed infinitiesĪn equivalence relation on a set of values is a boolean IEEE 754 floating-point values include finite nonzero values, For example, in a future release, synchronization may fail. ![]() Use instances for synchronization, or unpredictable behavior may In addition, this class provides several methods for converting aĬonstants and methods useful when dealing with aĬlass programmers should treat instances that are The Double class wraps a value of the primitive typeĭouble contains a single field whose type is ![]()
