Macro definitions are used in many ways, such as defining heights, judging iOS systems, tool classes, and documentation such as file paths and server-side API interfaces. In order to the macro can quickly locate and understand its function, we better in the definition of the time to put it into a specific header file, the following I would like to introduce some commonly used macros to classify, sub-file definition, I hope to be helpful.

has one-bit symbol bit s, eight-bit index E, and 23-bit ending number M. Convert to value v = (-1) ** S * 1. M * 2 ** (E-127 ). For example, 16.5 = 00010000.1 = 1.00001*2 ** 4 (becoming a normalized number), the sign bit is 0, and the index bit is 4 + 127 = 131 = 10000011 (because the index can be negative, the range of 8-Bit Signed numbers is-128 ~ 127. To use the unsigned number in a unified manner, add 127) and the ending number is 00001000000000000000000. After splicing, 16.5 of the memory

To http://blog.csdn.net/rnamatrix/article/details/5765462 Today, when using the numeric_limits class template functions Max and min in limits, an error occurs during compilation: [c-sharp] view plaincopyprint? error C2589: '(' : illegal token on right side of '::' error C2589: '(' : illegal token on right side of '::' I was puzzled. Then I suddenly thought that Max and Min may have been defined as macros. So I checked the header file and found that it must be in Windows. h Includes the

1. Definitions of 'global variable' in Tan haoqiang's book Variables defined in a function are local variables, while variables defined outside a function are external variables, and external variables are global variables. Global variables can be shared by other functions in this file. Their effective ranges start from the location of the defined variable to the end of the source file. The role of setting up global variables is to increase the channe

definition of a function are relatively simple. If {} is included, the function is defined. Otherwise, the function is declared.Example: extern double max (double D1, double D2); // Declaration 4. Unless the extern keyword extern exists, all variables are defined.Example: extern int I; // Declaration Int I; // Definition Programming style: 1. Do not put variable definitions in. H files, which may lead to repeated definition errors. 2. Use the static

When I first learned how to use python, especially when reading the source code of some libraries, I often see function definitions such as func (* ARGs, ** kwargs, this is a bit confusing. In fact, it is not difficult to understand the definition of function parameters. Let's talk about the Function Definition first. We all know that the following code defines a function funca. Def funca ():PassObviously, the function funca has no parameters (and doe

In general, we can use the following method to use the module, Modify the default ModuleThe ONet. xml file in the STS website definition has a default mod

The following two definitions are often seen in DelphiTypeTmouseproc = procedure (X,y:integer);Tmouseevent = procedure (X,y:integer) of Object;They look the same, but the actual meaning is different,Tmouseproc is only a single function pointer type;Tmouseevent is a function pointer to an object, which is the function/method of an Object/classThe difference is that the class method has a hidden parameter, self, which means that the two parameters are d
