* Add ceil implementation for 64-bit machines.Ulrich Drepper2009-08-241-0/+19
| | | | | | | On 64-bit machines we should not split doubles into two 32 bit integer and handle the words separately. We have wide registers. This patch implements a 64-bit ceil version. Ideally all other functions will be converted over time.
