WebA fixed-point number that is only scaled by binary point position is equivalent to a number in slope bias representation that has a bias equal to zero and a slope adjustment factor equal to one. This is referred to as binary point-only scaling or power-of-two scaling: real-world value = 2 fixed exponent × integer or WebA fixed-point value can be represented to within half of the precision of its data type and scaling. For example, a fixed-point representation with four bits to the right of the binary point has a precision of 2 -4 or 0.0625, which is the value of its least significant bit. tempe throwbacks
