Handle weird cases like (ceil 0 0.0) · 8b848def

Paul Eggert authored Nov 14, 2019

* src/floatfns.c (double_integer_scale): Distinguish Inf from NaN.
(rounding_driver): Handle (ceil 0 0.0) and (ceil 0 1.0e+INF).
* test/src/floatfns-tests.el (special-round): Add tests for
weird cases like this.

Avoid crash with (floor 0 0.0)
* src/floatfns.c (rounding_driver): Signal an arithmetic
error if divisor is 0.0 or -0.0, instead of crashing.
