what floating point

floating point numberrefers to data that is floating in the decimal place. Typically expressed as:N = M. R^e (ex: 0.10111x2110)where n is a floating-point number, M is the mantissa (mantissa), E is the order code (exponent), and R is the cardinality

Due to the binary relationship, most decimals under decimal are not perfectly represented in the binary, but can only be represented as infinite loop decimals.For example, 0.5 can be represented as 0.1,0.4 and can only be represented as 0.01100110011

After two or three days of study, I found that Delphi has many data types and is flexible. Especially strings and characters Type. At the same time, it is found that there are some special data types in Delphi, such as set. This is interesting and

As we all know, all data in a computer is represented in binary format, and floating point numbers are no exception. However, the binary representation of floating point numbers is not as simple as that of fixed points. First, clarify the concept
