Note, NONE of the other Decimal conversion functions are done within LIBGCC. All use sprintf/scanf. It is just that until GLIBC 2.32, we did not have the necessary support in GLIBC. I just don't think LIBGCC is the place to do this conversion, given the nature of decimal arithmetic. -- Michael Meissner, IBM IBM, M/S 2506R, 550 King Street, Littleton, MA 01460-6245, USA email: meiss...@linux.ibm.com, phone: +1 (978) 899-4797
