What is dot in binary?

In binary, a dot is represented as 00101110. It is also known as a period or decimal point. The use of a dot in binary is similar to its use in decimal systems to indicate a fractional part of a number. In binary, the dot separates the integer part from the fractional part of a binary number. The position of the dot determines the weight of the digits in the fractional part, where each position represents a power of two. The dot is usually used in conjunction with the binary system to represent real numbers, such as 0.5 or 0.75.
