As an example of where precision is lost, a 16-bit unsigned integer (uint16) can only hold a value as large as 65,535 10. If unsigned 16-bit integers are used to represent values from 0 to 131,070 10, then a scale factor of 1 ⁄ 2 would be introduced, such that the scaled values correspond exactly to the real-world even integers.
The VisSim company used fx m. b to denote a binary fixed-point value with b total bits and m bits in the integer part; that is, a b-bit integer with scaling factor 1/2 b−m. Thus fx1.16 would mean a 16-bit number with 1 bit in the integer part and 15 in the fraction. [13] The PS2 GS ("Graphics Synthesizer") User's Guide uses the notation s: m ...
That is, a 16-bit signed (two's complement) integer, that is implicitly multiplied by the scaling factor 2 −12. In particular, when n is zero, the numbers are just integers. If m is zero, all bits except the sign bit are fraction bits; then the range of the stored number is from −1.0 (inclusive) to +1.0 (exclusive). The m and the dot may be ...

One W bit, equivalent to the REX prefix's W bit, specifies a 64-bit operand; for non-integer instructions, it is a general opcode extension bit. Four vĚ… bits are the complement of an additional source register index. One L bit indicates the vector length; 0 for 128-bit SSE (XMM) registers, and 1 for 256-bit AVX (YMM) registers.
In computing, the least significant bit (LSb) is the bit position in a binary integer representing the binary 1s place of the integer. Similarly, the most significant bit ( MSb ) represents the highest-order place of the binary integer.
A dual-modulus prescaler is one that has the ability to selectively divide the input frequency by one of two (normally consecutive) integers, such as 32 and 33. Common fixed-integer microwave prescalers are available in modulus 2, 4, 8, 5 and 10, and can operate at frequencies in excess of 10 GHz. [1]
However, since division almost immediately introduces infinitely repeating sequences of digits (such as 4/7 in decimal, or 1/10 in binary), should this possibility arise then either the representation would be truncated at some satisfactory size or else rational numbers would be used: a large integer for the numerator and for the denominator.
