JavaScript learning notes operator (continued), javascript learning notes I. Multiplication Operators 1. Multiplication :* Special rules for multiplication operators: If the operands are all numeric values, they are calculated by regular multiplication. If the product exceeds the range indicated by the ECMAscript value, infinity or-infinity is returned.If one of the operands is NaN, the returned result is N

0, return false * If the OP count is null, return True * If the OP count is NaN, return True * If the OP count is undefined, there's a mistake. !! sblue, the first not operator returns a Boolean value. The second not will be negative for this boolean value The logical AND operation does not necessarily return a Boolean value: * If one of the operands is an object and the other is a Boolean value, return the object. * If two operands are objects, the second object is returned. * If a shipment c

problems, NaN makes it possible to simply continue the loop to perform operations that have no errors, even if a loop has made such an error. You might think that, now that Java has an exception handling mechanism, you might be able to achieve the same effect by capturing and ignoring exceptions. However, you know that the IEEE standard is not designed for Java alone, and that different languages handle exceptions differently, which makes it more difficult to migrate code. Moreover, not all lan

-point type .The Java language's floating-point type defaults to a double type, and you can add D or D after a floating-point number to force the specified variable to be a double type.If you want Java to treat a floating-point type value as a float type, you should immediately follow the value of F or F after this floating-point type.Java also provides three special floating-point values, positive infinity, negative

Blog.aikilis.com2471.html if the range of each data in the problem is clear, the infinite limit setting is not a problem. If it is not clear, many programmers use 0x7fffffff as the infinity, because this is the largest 32-bitint. If this infinity is only used for general comparison (for example, to obtain the minimum min variable), then 0x7fffff Http://blog.aikilis.com/2471.html if the scope of the data in

Python built-in functions (22) -- float, python built-in 22 float English document: Classfloat([X]) Return a floating point number constructed from a number or stringX. If the argument is a string, it shoshould contain a decimal number, optionally preceded by a sign, and optionally embedded in whitespace. The optional sign may be'+'Or'-';'+'Sign has no effect on the value produced. the argument may also be a string representing a NaN (not-a-number), or a positive or negative

exponent part of the special infinity value is alsoEMax + 1 = 128, but the infinite ending number field must be zero. Infinity is used to express the overflow problem in computing. For example, when two extremely large numbers are multiplied, although the two operands can be saved as floating-point numbers, the result may be as large as it cannot be saved as a floating-point number, but must be rounded. Ac

This article describes the attributes and methods of the Number object of the JavaScript native object. This article describes the syntax, MAX_VALUE, MIN_VALUE, NaN, and other attributes or methods for creating the Number object, for more information, see Syntax for creating a Number object: The Code is as follows: Var myNum = new Number (value );Var myNum = Number (value ); When Number () and operator new are used as constructors, it returns a newly created Number object. If the new operator i

To create the syntax for a number object: Copy Code code as follows: var myNum = new number (value); var myNum = number (value); When number () and operator new are used together as constructors, it returns a newly created number object. If you do not use the new operator to call number () as a function, it converts its arguments to an original numeric value and returns this (NaN) if the conversion fails. Max_value The Max_value property is the largest number that can
