Best way to handle the ratio which cannot be represented as floating point numbers. I need to calculate the ratio of the form: s=sum_1^3 q_i p_i=(q_i)/(sum_1^3q_i} where q_i >0. One problem is that q_i are too small that they can not represented as floating point numbers, then I can try logarithms z_i=log(q_i) and log(pi)=log(q_i)−log(q_1+q_2+q_3), at this moment, I know log(q_1)=−2012,log(q_2)=−2013,log(q_3)=−2014, but how to deal with log(q_1+q_2+q_3), any one could give me some idea?
