Use DBL_DIG to compute how much buffer space to use here.
2002-04-26 Christopher James Lahey <clahey@ximian.com>
* gal/util/e-util.h (E_ASCII_DTOSTR_BUF_SIZE): Use DBL_DIG to
compute how much buffer space to use here.
* gal/util/e-xml-utils.c (e_xml_set_double_prop_by_name): Use
DBL_DIG here to decide how many digits to print.
