WebTo convert a fixed-point number to floating-point, one may convert the integer to floating-point and then divide it by the scaling factor S. This conversion may entail rounding if the integer's absolute value is greater than 224(for binary single-precision IEEE floating point) or of 253(for double-precision).

WebV Fixed-Point Numbers. A fixed-point number consists of a whole or integral part and a fractional part, with the two parts separated by a radix point ( decimal point in radix 10, binary point in radix 2, and so on). The position of the radix point is almost always implied and thus the point is not explicitly shown.
