Google couldn't open it, and then Baidu ...... Lima ...... Baidu's IQ is exposed at a moment, and the desired results are not found at all. It's awesome to make a decisive 360 search. The basic data types of Objective-c are: int/long int /. Suddenly I am in a mess ...... There are still many things to do. Let's give a brief answer here. In ObjectiveC, the length of int and long is determined by the operatin

Reason:Because the long type is System.Int64 (Long integer, which accounts for 8 bytes, representing 64-bit integers, the range is approximately-(10 of 19) to 10 of the square)The Long Binaryreader.readint64 () method reads a eight-byte signed integer from the current stream and advances the current position of the stream by 8 bytes.Eight bytes to eight bytes, so

Recently do the problem, often meet the scope is 2^63, take mold 2^64 this topic. When encountering this restriction, you should think of the unsigned long long type.Can be succinctly declared as a typedef unsigned long long ull. Thus, if an integer of type ull overflows, it is equivalent to modulo 2^64. Because the ra

Title Link: http://acm.hdu.edu.cn/showproblem.php?pid=5666Test instructions: There is a line x+y=n, to find the line and the axis of the triangle enclosed by how many integer points, not on the axis and line, so that the result of the P-remainderThe obvious answer is (1+2+3+...+a-2)%P = ((A-1) (a-2)/2)%P;Because the range of a and p are relatively large, the direct multiplication will explode ll's, so you can use the idea of a fast power matrix;X*y = 2*X*Y/2; Y is an even number;X*y = x + 2*x*y/

Everything in Java is an object, because there are basic data types.Basic data types have a corresponding base data Type Packager, and their base data Type Packager is an object.J2SE 5.0 introduces boxing and unboxing, which are the relationship between the basic data type and the basic data Type PackagerLong and longLong's inheritance relationship:A few messages:1, long by final modification, not variable2.

The most recent use of the NHibernate mapping type is the CLOB field when inserting data to find the number of bytes (one half-width character one byte, one full-width character two bytes) between 2000-4000 times wrong (ORA-01461: You can only insert a Long value assignment for a long column). After constantly looking for information and their own test the problem is finally resolved, below I will own exper
