Abstract:
A method of calculating xM/N, x having a range and M and N integers. The range of x is partitioned into a selected number of intervals and a determination is made as to the interval into which x falls. x is normalized with a normalization factor calculated for the interval into which x falls to obtain a normalized value xnull within a normalized range. A value of xnullM/N is calculated over the normalized range and a value for xM/N is calculated by multiplying the calculated value of xnullM/N by a renormalization factor calculated for the interval in which x falls.
