-/* By default, SQLite will use long double if the long double type
-** actually provides higher resolution than double.  This use or non-use
-** of long double is switchable at run-time by a test-control. Dekker
-** algorithms are used for high-precision floating point when long double
-** is not available.
-**
-** Having the run-time option to enable/disable long double support
-** causes problems for some compiler tool chains.  So the following
-** compile-time option is available to permanently enable/disable the use
-** of long double.

-**    -DSQLITE_USE_LONG_DOUBLE=0      Omit all use of "long double" from
-**                                    the code. Instead, the Dekker algorithm
-**                                    is always used when high-precision
-**                                    floating point is required.

-**    -DSQLITE_USE_LONG_DOUBLE=1      Always use long double when high
-**                                    precision is needed. Never fall back
-**                                    to using Dekker algorithms.
-**
-** If the SQLITE_USE_LONG_DOUBLE macro is not defined, then the determination
-** of whether or not to use long double is made at run-time.
