patch faster long2mpz #18

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 

long2mpz becomes faster reading two digits at a time, each digit having
SHIFT=15 digits. 
On a computer with Debian, Pentium M 1.60GHz the tests in mpmath run 1%
faster with this patch.

There is a misprint: ...each digit having SHIFT=15 bits.

A faster long2mpz was added to the svn repository. Can you test the svn 
version? (A
good revision to grab is r48.)

I tested the svn version with mpmath 0.10. It is approximately 4% faster.

I tried the svn version 48 with mpmath 0.10; it is 2% faster than gmpy-1.03 with
my patch.
Great function mpz_import !
