annotate tests/automated/lisp-reader-tests.el @ 4678:b5e1d4f6b66f
Make #'floor, #'ceiling, #'round, #'truncate conform to Common Lisp.
lisp/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* cl-extra.el (ceiling*, floor*, round*, truncate*):
Implement these in terms of the C functions; mark them as
obsolete.
(mod*, rem*): Use #'nth-value with the C functions, not #'nth with
the CL emulation functions.
man/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* lispref/numbers.texi (Bigfloat Basics):
Correct this documentation (ignoring for the moment that it breaks
off in mid-sentence).
tests/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* automated/lisp-tests.el:
Test the new Common Lisp-compatible rounding functions available in
C.
(generate-rounding-output): Provide a function useful for
generating the data for the rounding functions tests.
src/ChangeLog addition:
2009-08-11 Aidan Kehoe <kehoea@parhasard.net>
* floatfns.c (ROUNDING_CONVERT, CONVERT_WITH_NUMBER_TYPES)
(CONVERT_WITHOUT_NUMBER_TYPES, MAYBE_TWO_ARGS_BIGNUM)
(MAYBE_ONE_ARG_BIGNUM, MAYBE_TWO_ARGS_RATIO)
(MAYBE_ONE_ARG_RATIO, MAYBE_TWO_ARGS_BIGFLOAT)
(MAYBE_ONE_ARG_BIGFLOAT, MAYBE_EFF, MAYBE_CHAR_OR_MARKER):
New macros, used in the implementation of the rounding functions.
(ceiling_two_fixnum, ceiling_two_bignum, ceiling_two_ratio)
(ceiling_two_bigfloat, ceiling_one_ratio, ceiling_one_bigfloat)
(ceiling_two_float, ceiling_one_float, ceiling_one_mundane_arg)
(floor_two_fixnum, floor_two_bignum, floor_two_ratio)
(floor_two_bigfloat, floor_one_ratio, floor_one_bigfloat)
(floor_two_float, floor_one_mundane_arg, round_two_fixnum)
(round_two_bignum_1, round_two_bignum, round_two_ratio)
(round_one_bigfloat_1, round_two_bigfloat, round_one_ratio)
(round_one_bigfloat, round_two_float, round_one_float)
(round_one_mundane_arg, truncate_two_fixnum)
(truncate_two_bignum, truncate_two_ratio, truncate_two_bigfloat)
(truncate_one_ratio, truncate_one_bigfloat, truncate_two_float)
(truncate_one_float, truncate_one_mundane_arg):
New functions, used in the implementation of the rounding
functions.
(Fceiling, Ffloor, Fround, Ftruncate, Ffceiling, Fffloor)
(Ffround, Fftruncate):
Revise to fully support Common Lisp conventions. This means:
-- All functions have optional DIVISOR arguments
-- All functions return multiple values; see #'values
-- All functions do their arithmetic with the correct number types
according to the contamination rules.
-- #'round and #'fround always round towards the even number
in ambiguous cases.
* doprnt.c (emacs_doprnt_1):
* number.c (internal_coerce_number):
Call Ftruncate with two arguments, not one.
* floatfns.c (Ffloat):
Correct this, if NUMBER is a bignum.
* lisp.h:
Declare Ftruncate as taking two arguments.
* number.c:
Provide scratch_ratio2, init it appropriately.
* number.h:
Make scratch_ratio2 available.
* number.h (BIGFLOAT_ARITH_RETURN):
* number.h (BIGFLOAT_ARITH_RETURN1):
Correct these functions.
