blamed for random crashes in the following cases: output in base 32 for
|
| 59 |
|

fixnums on a 64 bit target.

Algorithmic changes
|
| 645 |
|
|
-------------------
|
| 646 |
|
|
|
| 647 |
|
|
* Speed up the multiplication of large numbers by use of an FFT based
|
| 648 |
|
|
algorithm (Schönhage-Strassen). The improvement is noticeable when both
|
| 649 |
|
|
factors have at least 1250 words = 40000 bits = 12000 decimal digits.
|
| 650 |
|
|
|
| 651 |
|
|
* Speed up the functions `cl_I gcd (const cl_I&, const cl_I&)' and
|
| 652 |
|
|
`cl_I xgcd (const cl_I&, const cl_I&, cl_I*, cl_I*)' by a factor
|
| 653 |
|
|
of 1.5. Simple trick.
|
| 654 |
|
|
|
| 655 |
|
|
* Speed up the function `cl_boolean sqrtp (const cl_I&, cl_I*)' using a
|
| 656 |
|
|
trick from Henri Cohen.
|
| 657 |
|
|
|
| 658 |
|
|
* Fixed an endless loop in the function `uint32 gcd (uint32, uint32)'
|
| 659 |
|
|
which occurred when one of the arguments is zero.
|
| 660 |
|
|
|
| 661 |
|
|
* Fixed an endless loop in the function `cl_I factorial (uintL)'.
|

Implementation changes
|
| 664 |
|
|
----------------------
|
| 665 |
|
|
|
| 666 |
|
|
* <cl_io.h> now uses iostreams by default instead of stdio FILE pointers.
|
| 667 |
|
|
(Reported by Tito Flagella.)
|
| 668 |
|
|
|
| 669 |
|
|
* Fixed linking error when compiling without -O.
|
| 670 |
|
|
(Reported by Tito Flagella.)
|
| 671 |
|
|
|
| 672 |
|
|
* Fixed syntax error in <cl_input.h>.
|
| 673 |
|
|
(Reported by Tito Flagella.)
|
| 674 |
|
|
|
| 675 |
|
|
* Fixed syntax errors in src/cl_DS.h and src/cl_FF_plus.h.
|
| 676 |
|
|
(Reported by Marcus Daniels.)
|
| 677 |
|
|
|
| 678 |
|
|
* More portability fixes.
|
| 679 |
|
|
|
| 680 |
|
|
* Configuration now supports the --srcdir option.
