GMP functions that take doubles choke on non-finite values, avoid that.
src/ChangeLog addition:
2015-05-10 Aidan Kehoe <kehoea@parhasard.net>
* floatfns.c (double_to_integer):
Rename this from float_to_int to fit our newer, bignum-compatible
terminology.
GMP can signal SIGFPE when asked to turn NaN or infinity into a
bignum, and we're not prepared to handle that signal if the OS float
library routines don't do that, so check for those values
explicitly.
* floatfns.c (ceiling_two_float):
* floatfns.c (ceiling_one_float):
* floatfns.c (floor_two_float):
* floatfns.c (floor_one_float):
* floatfns.c (round_two_float):
* floatfns.c (round_one_float):
* floatfns.c (truncate_two_float):
* floatfns.c (truncate_one_float):
Call double_to_integer() with its new name.
* number.c:
Don't use the {bignum,ratio,bigfloat}_set_double functions
directly here, with GMP they can choke when handed non-finite C
doubles, call Ftruncate() and the new float_to_bigfloat() from
floatfns.c. Maybe we should extend number-gmp.c with GMP-specific
implementations that check for non-finite values.
tests/ChangeLog addition:
2015-05-10 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Backslash a few parentheses in the first column for the sake of
fontification.
* automated/lisp-tests.el:
Check that the rounding functions signal Lisp errors correctly
when handed positive and negative infinity and NaN.
