negative operands in the floating point domain also.

that doesn't begin with a digit, it's most likely NaN or Inf.
We can turn that into an exception.

turn it into the printed representation #<bad-float>.

(divi): Uses to_float.

(isqrt): Renamed to sqroot. Floating support.
(evenp, oddp, exptmod, gcd): Work with integers, not floats.

which are already implied by the switch case.

* parser.l: FLO and FLODOT cases had to be reordered because
the lex trailing context counts as part of the match length,
causing 3.0 to be matched as three characters with 0 as
the trailing context. The cases are split up to eliminate
a flex warning.
* stream.c (vformat): Support bignum in floating point
conversion. Bugfixes: floating point conversion was
accessing obj->fl.n instead of using n.
Changed some if/else ladders to switches.
|
|
|
|
|
|
|
|

(minus): Floating point support.
* mpi-patches/mpi-to-double (mp_to_double): Re-apply lost

Didn't refresh patch last time, then did a make distclean.

result is in the fixnum range.
Implemented FLNUM cases, except for adding a FLNUM
to BGNUM.
(minus, mul): Use num_fast when the cnum value is in the fixnum range.
(int_flo): New function.

refers to zero-length sequence just past the end of the array or list.
Also, fixed out of bounds memmoves in replace_vec.

operation.

* arith.c (plus, minus, mul, gt, ge, lt, le, exptmod, gcd): Remove
trailing abort; we already marked uw_throwf as noreturn. This hack
should not be needed in functions where the last statement is a throw.
(trunc, expt): Repeated error case handled in one place. Temp variable
used to avoid two calls to mp_clear. Call to abort removed.

by moving throw past mp_clear calls. Call to abort removed.

* txr.1: Sections for zerop and bignump created. Changed reference
to numberp to fixnump.
|

(trunc): Plugged memory leaks. Straightened out semantics
with negative modulus. (Residue comes out negative).
|
|
|
|

code like 1 << n, where n exceeds the width of the type int.

trunc from lib.c.
* lib.c (trunc): Removed.

(plus, minus): Bugfix: must not pass signed values to mp_add_d and
mp_sub_d functions.
(mul): Must not pass signed value to mp_mul_d. Also, fixed type check
on wrong argument in the (TAG_PTR, TAG_NUM) case.
|
| |
|
|
|
|
|
| |
* arith.txr (normalize): Bugfix: was not turning +/- NUM_MAX bignums
into fixnums.
|
|

* arith.txr (highest_bit): Missing #else added, fixing
SIZEOF_PTR == 4 case.
|
|
|
|

* arith.txr (highest_bit): Oops, half the logic for
the 64 bit case was missing due to to a cut and paste mistake.
|
|
|
|

* mpi-patches/add-mp-set-intptr (mp_set_intptr): Revised patch.
Local variable v should be int_ptr_t not unsigned long.
Also, the mp_set interface doesn't set the sign; it's an unsigned
interface. We must do that ourselves.
* mpi-patches/fix-mult-bug: The main multiplication function is
also broken in the same way, requiring the cast.
* mpi-patches/mpi-set-double-intptr: Fixed use of wrong type for
local variable v.

Bignums, based on Michael Fromberger's MPI library, are integrated
into the input syntax, stream output, equality testing, the garbage
collector, and hashing.
The plus operation handles transitions between fixnums and bignums.
Other operations are still fixnum only.
* Makefile (CFLAGS): Add mpi directory to include file search.
(OBJS): Include new arith.o module and all of MPI_OBJS.
(MPI_OBJS, MPI_OBJS_BASE): New variables.
* configure (mpi_version, have_quilt, have_patch): New variables.
Script detects whether patch and quilt are available. Unpacks
mpi library, applies patches. Detects 128 bit integer type.
Records more information in config.h about the sizes of types.
* dep.mk: Updated.
* depend.txr: Make work with paths that have directory components.
* eval.c (eval_init): Rename of nump to fixnump.
* gc.c (finalize, mark_obj): Handle BGNUM case.
* hash.c: (hash_c_str): Changed to return unsigned long
instead of long.
(equal_hash): Handle BGNUM case.
(eql_hash): Handle bignums with equal-hash, but other
objects as eq.
* lib.c (num_s): Variable renamed to fixnum_s.
(bignum_s): New symbol variable.
(code2type): Follow rename of num_s. Handle BGNUM case.
(typeof): Follow rename of num_s.
(eql): Handle bignums using equal, and other types using eq.
(equal): Handle BGNUM case.
(chk_calloc): New function.
(c_num): Wording change in error message: is not a fixnum.
(nump): Renamed to fixnump.
(bignump): New function.
(plus): Function removed, reimplemented in arith.c.
(int_str): Handle integers which are too large for wcstol
using bignum conversion. Base 0 is no longer passed to
wcstol but converted to 10 because the special semantics
for 0 would be inconsistent for bignums.
(obj_init): Follow rename of num_s. Initialize bignum_s.
