If we sprintf(buffer,"%#.3g", 99.99);, we get 100.0 - with 4 significant digits - while we should be getting 100., with 3 significant digits.
This is because, initially, we find the power of 10 to be 2; then we translate significant digits to precision, setting the precision to 1. But after this happens, we perform rounding with precision 1, so that the power of 10 becomes 3...
