integer-expt and multiply/divide. Inexacts and fractions no longer
supported (they happened to work before for left shifts, but not
right). Don't really need inexacts and fractions, since ash is
documented as a "bitwise operation", and all the rest of those only
take exact integers.
scm_t_intmax values.
(scm_uint2str): New, for scm_t_uintmax.
(scm_iint2str): Argument type changed to scm_t_intmax,
reimplemented in terms of scm_uint2str.
* configure.in (isinf): Let configure find the isinf() function
on MinGW32 systems.
2004-09-03 Stefan Jahn <stefan@lkcc.org>
* threads.c (scm_threads_mark_stacks): Fixed local variable
definitions.
* strings.c (scm_i_substring_copy, s_scm_string_append): Fixed
local variable definitions.
* stime.c (_POSIX_C_SOURCE): Do not define this item on
MinGW32 because it conflicts with its pthread headers.
(s_scm_mktime): Consider the HAVE_STRUCT_TM_TM_ZONE define.
(s_scm_strftime): Using scm_from_locale_string() instead of
scm_makfrom0str().
* posix.c (s_scm_putenv): Fixed typo in the !HAVE_UNSETENV
part.
* numbers.c (scm_init_numbers): Removed check_sanity() call
inside GUILE_DEBUG. The function has been removed somewhen...
* filesys.c (_POSIX_C_SOURCE): Do not define this item on
MinGW32 because it conflicts with its pthread headers.
2004-09-03 Stefan Jahn <stefan@lkcc.org>
* srfi-1.c, srfi-1.h: Renamed any 'lst1' into 'list1' because
lst1 is a #define on Win32 systems.
(SCM_VALIDATE_STRING_COPY): Deprecated. Replaced all uses with
SCM_VALIDATE_STRING plus SCM_I_STRING_CHARS or
scm_to_locale_string, etc.
(SCM_VALIDATE_SUBSTRING_SPEC_COPY): Deprecated. Replaced as
above, plus scm_i_get_substring_spec.
* regex-posix.c, read.c, random.c, ramap.c, print.c, numbers.c,
hash.c, gc.c, gc-card.c, convert.i.c, backtrace.c, strop.c,
strorder.c, strports.c, struct.c, symbols.c, unif.c, ports.c: Use
SCM_I_STRING_CHARS, SCM_I_STRING_UCHARS, and SCM_I_STRING_LENGTH
instead of SCM_STRING_CHARS, SCM_STRING_UCHARS, and
SCM_STRING_LENGTH, respectively. Also, replaced scm_return_first
with more explicit scm_remember_upto_here_1, etc, or introduced
them in the first place.
(scm_number_p): Export as "number?" to Scheme.
(scm_is_complex, scm_is_number): New.
(scm_c_make_rectangular, scm_c_make_polar): New.
(scm_make_rectangular, scm_make_polar): Use above.
(scm_c_real_part, scm_c_imag_part, scm_c_magnitude, scm_c_angle):
New.
(scm_make_complex): Discouraged by moving to discouraged.h and
discouraged.c. Replaced all uses with scm_c_make_rectangular.
(scm_i_short2big, scm_i_int2big, scm_i_uint2big, scm_i_size2big,
scm_i_ptrdiff2big, scm_i_long_long2big, scm_i_ulong_long2big):
Removed prototypes.
(scm_make_real, scm_num2dbl, scm_float2num, scm_double2num):
Discouraged by moving to discouraged.h and discouraged.c.
Replaced all uses with scm_from_double.
(scm_num2float, scm_num2double): Discouraged by moving prototype
to discouraged.h and rewriting in terms of scm_to_double.
Replaced all uses with scm_to_double.
(scm_to_double): Do not implement in terms of scm_num2dbl, use
explicit code.
(scm_from_double): Do not implement in terms of scm_make_real, use
explicit code.
SCM_INUM): Deprecated by reenaming them to SCM_I_INUMP, SCM_I_NINUMP
and SCM_I_INUM, respectively and adding deprecated versions to
deprecated.h and deprecated.c. Changed all uses to either use the
SCM_I_ variants or scm_is_*, scm_to_*, or scm_from_*, as appropriate.
not accept inexact integers.
* validate.h, deprecated.h (SCM_VALIDATE_INUM, SCM_VALIDATE_INUM_COPY,
SCM_VALIDATE_BIGINT, SCM_VALIDATE_INUM_MIN,
SCM_VALIDATE_INUM_MIN_COPY,
SCM_VALIDATE_INUM_MIN_DEF_COPY,SCM_VALIDATE_INUM_DEF,
SCM_VALIDATE_INUM_DEF_COPY, SCM_VALIDATE_INUM_RANGE,
SCM_VALIDATE_INUM_RANGE_COPY): Deprecated because they make the
fixnum/bignum distinction visible. Changed all uses to scm_to_size_t
or similar.
Rewritten using the same logic as scm_to_signed_integer and
scm_to_unsigned_integer, respectively, which is better(tm). Also,
use CHAR_BIT instead of hardcoding 8.
(LLONG_MIN, LLONG_MAX, ULLONG_MAX): Removed and used
SCM_I_LLONG_MIN etc. instead.
* numbers.h (SCM_MAKINUM, SCM_I_MAKINUM): Renamed SCM_MAKINUM to
SCM_I_MAKINUM and changed all uses.
(fx): Removed.
(scm_dblprec, fx_per_radix, init_dblprec, init_fx_radix,
number_chars): New, to support variable radices.
(idbl2str): Use above instead of the old base-10 only tables.
(iflo2str): Pass on new RADIX argument to idbl2str.
(scm_number_to_string): Pass radix to iflo2str.
(scm_print_real, scm_print_complex): Explicitly pass radix 10 to
iflo2str.
(scm_init_numbers): Call init_dblprec and init_fx_radix for all
possible radices.
mem2uinteger, mem2decimal_from_point, mem2ureal): Cast char to int for
ctype.h tests, to avoid warnings from gcc on HP-UX about char as array
subscript. Reported by Andreas Vögele.
Also cast through unsigned char to avoid passing negatives to those
macros if input contains 8-bit values.
rounding in x+0.5 when x is a big value already an integer. In
certain hardware rounding cases x+0.5 can give an adjacent integer,
leading to that as the result, when we really just wanted x itself.
