Hello Laurent_R,

Wow really nice explanation, it helped my to understand many things. Well I was planning to increase the accuracy of a timing process that I want to use, but as everyone pointed out the number that I am going to get is so small that probably will be out of range.

At this point I think I should look for 32 bit floating points with positive and negative range values. I think they will do my work just fine, and in case that they can I will take it from there and start digging again to my next problem.

Again I want to say thank you, for your time and effort. You helped me to understand a lot.
