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.

eb927cb95c * numbers.c (scm_exact_p, scm_inexact_p): Throw error for non-numbers. 2003-11-19 02:38:37 +00:00

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

cef6deaff1 (Manual Conventions): Double-quote some statements formerly 
single-quoted.  Remove some redundant quotes around code.  Clarify
meaning of `iff' further for those that didn't get it the first time
'round (like me).  Make graphical indicators samples, not code.  Put
results of evaluation on the same line as @result symbols.  Use @print
example as example of total usage, and remind readers not to forget
the difference.

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.
