to string conversions and vice versa" Initial import of the dtoa.c code and custom wrappers around it to allow its usage from the server code. Conversion of FLOAT/DOUBLE values to DECIMAL ones or strings and vice versa has been significantly reworked. As the new algoritms are more precise than the older ones, results of such conversions may not always match those obtained from older server versions. This in turn may break compatibility for some applications. This patch also fixes the following bugs: - bug #12860 "Difference in zero padding of exponent between Unix and Windows" - bug #21497 "DOUBLE truncated to unusable value" - bug #26788 "mysqld (debug) aborts when inserting specific numbers into char fields" - bug #24541 "Data truncated..." on decimal type columns without any good reason"
