Thanks Gilles. I checked NUMBERS-193 and i have an implementation of DD and i will put it in *.ext package (TBD) along with some tests. Do i have to look at Dfd.java or something, because these dfd classes in math legacy core have lots of hard-coded decimals in there. Do these need to be copied to DD or just implement the high/low part, add, multiply and checks for overflows?
