FP_DIGITS

The SQLITE_DBCONFIG_FP_DIGITS setting is a small integer that determines the number of significant digits that SQLite will attempt to preserve when converting floating point numbers (IEEE 754 "doubles") into text. The default value 17, as of SQLite version 3.52.0. The value was 15 in all prior versions.

This option takes two arguments which are an integer and a pointer to an integer. The first argument is a small integer, between 3 and 23, or zero. The FP_DIGITS setting is changed to that small integer, or left unaltered if the first argument is zero or out of range. The second argument is a pointer to an integer. If the pointer is not NULL, then the value of the FP_DIGITS setting, after possibly being modified by the first arguments, is written into the integer to which the second argument points.
