The total value of an expression returned by the SUM function. This function is also very useful. Let's take a look at the detailed usage of this function.
The syntax of the SUM function is:
The Code is as follows:

Note: If you enter a 10-digit number on the keyboard, the program will automatically convert it into a 16-bit binary number. Then, every four digits is a number, and write the function to calculate their sum.
The Code is as follows:
Char SumOfQuaters (unsigned short n){Int c = 0;Int I = 4;Do{C + = n 15; // bitwise and operation of n and 15 (Binary bit 1111), we can get the number of four lower bits. Then
+=Implements a numeric addition function that returns the sum of two digits. Parameter validation is required and throws an exception if the parameter is not a number or is empty.
Array_sum () Definition and usageThe array_sum () function returns the sum of all values in the array.
If all values are integers, an integer is returned. If one or more of the values are floating-point numbers, the return value is floating-point numbers.
In versions earlier than PHP 4.2.1, the input array itself is modified to convert the string value to a value (in most cases, it is converted to zero,
In C ++ functions, the C ++ Sum function can use SUM for any Sum, but cannot use any name to access several other indefinite parameters, however, the other parameters on the stack are arranged in the high address direction of the SUM parameter in order.
Therefore, it is easy

Label:Sum is the standard SUM function in an SQL statement, and the SUM function returns null if there are no records that match the criteria. But in most cases, we want it to return 0 instead of NULL if the condition record is not met, so we can use the following method, for example: SELECT COALESCE (
A=sum (A)% column sumB=sum (a,2)% row sumC=sum (A (:))% matrix summationSuppose A is a matrix:Sum (a) sums the numbers in a column with the object for each of the columns in matrix A.SUM (a,2) sums the numbers in a row with each behavior object of matrix A.A (:, 1) is the first column of the matrixA (1,:) is the first line of the Matrix, and so on.
