WebOct 7, 2003 · Fixed-point math typically takes the form of a larger integer number, for instance 16 bits, where the most significant eight bits are the integer part and the least significant eight bits are the fractional part. Through the simple use of integer operations, the math can be efficiently performed with very little loss of accuracy. WebNov 23, 2024 · The term "Fixed-Point" refers to the position of the binary point. The binary point is analogous to the decimal point of a base-ten number, but since this is binary rather than decimal, a different term is used. In binary, bits can be either 0 or 1 and there is no separate symbol to designate where the binary point lies.
