Every IEEE-754 double can be represented exactly as a decimal floating-point
value, but some doubles require more than 16 or 26 significant digits.

<li><p>
The order of the buffer pointer and buffer size parameters in the built-in
snprintf() implementation is reversed from the order used in standard-library
implementations.






</ol>

<p>
In spite of the disadvantages, the developers believe that having a built-in
printf() implementation inside of SQLite is a net positive.

<li><p>
The order of the buffer pointer and buffer size parameters in the built-in
snprintf() implementation is reversed from the order used in standard-library
implementations.

<li><p>
The built-in printf() implementation does not handle posix positional referencing
modifiers that allow the order of arguments to printf() to be different from the
order of the %-substitutions.  In the built-in printf(), the order of the arguments
must exactly match the order of the %-substitutions.
