raw data converter

JavaScript provides 5 raw data types: Number, String, Boolean, NULL, and undefined. For the first 3, number, String, and Boolean, the encapsulated object is provided with the constructor for number (), string (), and Boolean (). The following code shows the differences between the original data types and their encapsulated objects:A primitive Numbervar n = 100;co

When we do some image processing, we often involve RGB565 this kind of image data format. Because of its 2 bytes per pixel, the use of RGB565 without pixel transparency can basically guarantee the color of the image and reduce the size of the image data, saving bandwidth. Therefore, RGB565 will be a common format for the more economical image processing.Here's a description of how to convert a RGB565 of

TypeAnother type with only one value is null, and it has only one private value, NULL, which is its literal. The value undefined is actually derived from the value null, so ECMAScript defines them as equal.Although the two values are equal, they have different meanings. Undefined is a value that is assigned to a variable when it is declared but not initialized, and null is used to represent an object that does not already exist (this is briefly described when discussing the typeof operator). If

Java defines eight basic types of data:,,,,,, byte short int long char float double and boolean .The base type is often referred to as a simple type.These basic types can be divided into four groups: Integers-include:,,, byte short int and long , for integer signed numbers. Floating-point number-includes float and double , represents a number with fractional precision. Characters-include characters that represent symbols in the charac
