# Math 11 functions

Unlike some of the numeric methods of class StrictMathall implementations of the equivalent functions of class Math are not defined to return the bit-for-bit same results. This relaxation permits better-performing implementations where strict reproducibility is not required. By default many of the Math methods simply call the equivalent method in 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 Math methods.

Such higher-performance implementations still must conform to the specification for Math. The quality of implementation specifications concern two properties, accuracy of the returned result and monotonicity of the method. Accuracy of the floating-point Math methods is measured in terms of ulpsunits 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. 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 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. Not all approximations that have 1 ulp accuracy will automatically meet the monotonicity requirements. The platform uses signed two's complement integer arithmetic with int and long primitive types. The developer should choose the primitive type to ensure that arithmetic operations consistently produce correct results, which in some cases means the operations will not overflow the range of values of the computation.

The best practice is to choose the primitive type and algorithm to avoid overflow. In cases where the size is int or long and overflow errors need to be detected, the methods addExactsubtractExactmultiplyExactand toIntExact throw an ArithmeticException when the results overflow. For other arithmetic operations such as divide, absolute value, increment by one, decrement by one, and negation, overflow occurs only with a specific minimum or maximum value and should be checked against the minimum or maximum as appropriate.

In the foregoing descriptions, a floating-point value is considered to be an integer if and only if it is finite and a fixed point of the method ceil or, equivalently, a fixed point of the method floor. A value is a fixed point of a one-argument method if and only if the result of applying the method to the value is equal to the value. Special cases: If the argument is NaN, the result is 0.

If the argument is negative infinity or any value less than or equal to the value of Integer.If you're seeing this message, it means we're having trouble loading external resources on our website. To log in and use all the features of Khan Academy, please enable JavaScript in your browser.

The CBSE Class 11 mathematics syllabus tries to ensure that the basics of plus 2 Maths are covered for the students moving forward with their line of work. For obtaining desired marks, you must practice questions for earlier years to enhance your understanding of every chapter. There are 20 questions that are divided into four sections. The following table provides you with a clearer picture for you to understand the number of questions and marks from each section. This will help you stay in the loop when it comes to smooth and seamless examination preparations.

As you can see from the syllabus, a significant part of the question paper would involve problems from the chapter of relations and functions. Prior to jumping to the type of problems that appear in the exam, you need to understand the concept and the importance of such problems in your field of work. This will naturally help you relate better to real-world applications and you will be able to tackle several types of questions with aplomb.

In the context of Algebra, "Relations and Functions" is deemed to be the most significant aspect. Mathematically, relations and functions are two different words comprising of two different meanings. If you're not familiar with their usage, you may feel confused about the problems. Before delving more in-depth with the issues, here's a simple example to make you clear about the fundamental difference.

Let us consider Inlet, Outlet to be an ordered pair. When a relation is implemented, a relationship between Inlet and Outlet is setup. It can be said in other words that although every function can be considered to be relations, not every relationship is a function.

It makes you take decisions on the type of methods you need to implement while solving such problems. Relations and functions Class 11 will certainly be made easier courtesy Vedantu. Class 11 Maths Chapter 2 miscellaneous Solutions is something where you need the right insights and this is what you will get here.
