WebFor encoding purposes the mantissa M is further broken down; M = S * N * 2F, where S is the sign, N the number, and F a binary scaling factor. S can be either 1 or -1, F can be 0, 1, 2, or 3, and N can be any non-negative integer value. The example shows how the real value 10.0 could be described using this scheme.
