Kevin Ryde
084b1d8eec (scm_less_p): Remove spurious xisnan from frac+big case. 2003-12-02 21:36:39 +00:00
Kevin Ryde
2fa2d87937 (scm_real_part): Return fraction unchanged rather than converting to flonum. 2003-12-02 21:27:13 +00:00
Kevin Ryde
dd5130cadf (scm_make_ratio): Check for numerator equal to 
SCM_MOST_NEGATIVE_FIXNUM and bignum denominator the negative of that,
giving integer -1.
 2003-12-02 21:21:14 +00:00
Dirk Herrmann
2d0b85acf8 * modules.c (module_variable): Fixed (and thus simplified) the 
definition of SCM_BOUND_THING_P to reflect the fact that since
	after the 1.4 series of guile, obarrays only hold variable
	objects.

535f2a516a (scm_logand): It's "#b...", not "#\b...". 2003-11-30 00:59:40 +00:00
Marius Vollmer
fea8e14239 (scm_iprin1): use \xNN hexadecimal sequences when writing control 
characters in strings.
 2003-11-30 00:57:14 +00:00
Marius Vollmer
b645ea8c7e (scm_lreadr): Signal an error for invalid escape sequences in strings. 
Code cleanups too.

6bff13687c * eval.c (s_bad_define): New static identifier. 
(m_body): Fixed comment.

	(scm_m_define): Don't generate memoized code for definitions that
	are not on the top level.  As a consequence, no memoized code at
	all is generated for definitions any more: Top level definitions
	are executed immediately during memoization and internal
	definitions are handled separately in m_expand_body.

	(scm_unmemocopy, unmemocopy): Removed code for unmemoizing
	definitions.  Consequently, there is no unmemoizing code any more
	that might modify the environment.  Thus, the old scm_unmemocopy
	is removed and the old unmemocopy is renamed to scm_unmemocopy.

	(SCM_CEVAL): The SCM_IM_DEFINE keyword can no longer occur in
	memoized code.  Call EVALCAR for continuations.  Prefer !SCM_NULLP
	over SCM_NIMP in places, where the argument is known to be part of
	a proper list.

Marius Vollmer
28a6e1b0b6 (scm_drain_input): Bug fix: only access the port after checking that 
it indeed is one.

7f84824269 (scm_bit_extract): Use mpz functions, rearrange inum case 
to share some shifting.
 2003-11-21 00:33:44 +00:00
Kevin Ryde
ae38324d9c (scm_abs): Allocate a new real only for negatives, as done for bignums. 2003-11-21 00:07:13 +00:00
Kevin Ryde
753ac1e7e1 (scm_integer_expt): Don't mpz_init after scm_i_clonebig or 
scm_i_mkbig, since they do so already.  Don't mpz_clear a bignum SCM,
since gc does this.

c60e130c97 * numbers.c (scm_make_ratio): Rewritten to have a simpler 
structure.  Previously, not all cases with a negative denominator
were covered.

Marius Vollmer
02164269a7 * numbers.c (scm_i_fraction_equalp): Do not treat the return value 
of scm_equal_p as a C boolean, use SCM_FALSEP.  Previously, all
fractions were equal to each other regardless of value.  Ooops.

* numbers.c (scm_rationalize): Return an inexact result when given
inexact arguments.
 2003-11-19 03:50:26 +00:00

Marius Vollmer
d8592269ab (mem2decimal_from_point): use scm_divide instead of scm_divide2real 
when forming the fractional part.  This allows "#e1.2" to yield 6/5.

9ca20a9c88 * gen-scmconfig.c (main): remove public definition of 
SCM_SIZEOF___INT64 and SCM_SIZEOF_UNSIGNED___INT64 and add
direct typedef of long_long and ulong_long inside deprecated block
when appropriate.
 2003-11-18 06:10:39 +00:00
Rob Browning
1fe5648d31 move long_long and ulong_long definitions to 
gen-scmconfig.c so that we don't need to add SCM_SIZEOF___INT64
and SCM_SIZEOF_UNSIGNED___INT64 to the public namespace.

8b31d75b34 (scm_compile_shell_switches): Use scm_c_read_string for the "-e" 
option instead of scm_str2symbol.  This allows things like (@ ...) to
be specified for the entry point.
