D notation bug

[bplus]

bplus, the point was to show any buggy output by QB64 native double to string conversion as in your example Print (1D+17) * (1D+17) 
as you can see in your output you have two 1D+22 and no 1D+23, also you have two 1D+28 and no 1D+29
using the C snprintf function would show them correctly

It did, and I missed seeing the 22/23 and 28/29 repeats doing it the 2nd way! Definitely something buggy!
