ashinn	b16a214fee	sexp_bignum_sqrt is only needed if SEXP_USE_MATH is enabled.	2013-03-23 21:16:21 +01:00
Alex Shinn	7dfad8a293	Don't gc release until after normalizing ratios. ... Fixes issue #171.	2013-01-23 22:07:33 +09:00

Alex Shinn	c0b257db25	Fixing overflow checking in certain cases in bignum addition. ... (patch from Lorenzo)	2012-12-31 10:51:42 +09:00
Alex Shinn	7ae254fc28	More accurate square roots for bignums - compute via iteration rather ... than approximation via flonums for very large bignums.	2012-12-22 18:06:22 +09:00
Alex Shinn	d9f7c07f8e	It's not sufficient to call sexp_negate on a copy of complex numbers, ... since the negation can mutate the components. We need to make a deep copy.	2012-12-12 10:55:02 +09:00
Alex Shinn	122d8b8a00	Properly handling +nan.0 and infinite comparisons.	2012-11-10 20:53:16 +09:00
Alex Shinn	ab42ea2cfb	Coerce flonums to bignums instead of vice versa in comparisons. ... Need to do the same for flonums <=> ratios but the conversion is a hack right now.	2012-11-07 21:40:53 +09:00
Alex Shinn	93ba0926a7	Build fixes for plan9. Moving individual object files out of opt/ since plan9 mkfiles have issues with these.	2012-08-16 16:04:02 +09:00
