1999-06-23 Ulrich Drepper <drepper@cygnus.com> * manual/arith.texi: Document restriction of ndigit parameter of ecvt and friends. * misc/efgcvt.c: Define NDIGIT_MAX. (gcvt): Limit precision in sprintf call to NDIGIT_MAX. Do not dynamically allocate the static buffers. They are small enough. * misc/efgcvt_r.c: Define NDIGIT_MAX. (fcvt_r): Limit precision in snprintf call to NDIGIT_MAX. * misc/qefgcvt.c: Define NDIGIT_MAX. * misc/qefgcvt_r.c: Likewise. * misc/tst-efgcvt.c (special): Add test for large ndigit parameter.
