Int64

Int64, short for "64-bit signed integer," is a long integer value type and a data type commonly used to represent whole numbers within a specific range. The "Int" stands for integer, indicating that it is a whole number, and the "64" refers to the number of bits used to store the value.

In computer systems, bits are the basic units of information and can be either 0 or 1. With 64 bits, an Int64 data type can store 2^64 distinct values. However, since one bit is used to represent the sign of the number (positive or negative), an Int64 can represent values ranging from -2^63 to 2^63 - 1. The highest positive value that can be stored in an Int64 is 9,223,372,036,854,775,807, and the lowest negative value is -9,223,372,036,854,775,808.

The Int64 data type provides a wide range of values, making it useful for various applications where large whole numbers or precise calculations are required. It is commonly used in programming languages like C#, Java, and many others.

Operations on Int64 values, such as addition, subtraction, multiplication, and division, follow the rules of integer arithmetic. It's important to keep in mind that operations exceeding the maximum or minimum value of an Int64 can result in overflow or underflow, where the result goes beyond the representable range, leading to unexpected behavior or errors in calculations.

In summary, Int64 is a data type used to represent signed whole numbers using 64 bits, providing a wide range of values for various computational purposes.
