Robert Griesemer authored Apr 30, 2010

- fixed a couple of bugs in the process
  (shift right was incorrect for negative numbers)
- added more tests and made some tests more robust
- changed pidigits back to using shifts to multiply
  by 2 instead of add

  This improves pidigit -s -n 10000 by approx. 5%:

big: improved computation of "karatsuba length" for faster multiplies · 407dbb42

Robert Griesemer authored Apr 30, 2010

This results in an improvement of > 35% for the existing Mul benchmark
using the same karatsuba threshold, and an improvement of > 50% with
a slightly higher threshold (32 instead of 30):

big.BenchmarkMul           500	   6731846 ns/op (old alg.)
big.BenchmarkMul	   500	   4351122 ns/op (new alg.)
big.BenchmarkMul           500	   3133782 ns/op (new alg., new theshold)

Also:
- tweaked calibrate.go, use same benchmark as for Mul benchmark

big: implemented Karatsuba multiplication · b2183701

Robert Griesemer authored Apr 27, 2010

Plus:
- calibration "test" - include in tests with gotest -calibrate
- basic Mul benchmark
- extra multiplication tests
- various cleanups

This change improves multiplication speed of numbers >= 30 words
in length (current threshold; found empirically with calibrate):

The multiplication benchmark (multiplication of a variety of long numbers)
improves by ~35%, individual multiplies can be significantly faster.

gotest -benchmarks=Mul
big.BenchmarkMul	     500	   6829290 ns/op (w/ Karatsuba)
big.BenchmarkMul	     100	  10600760 ns/op

There's no impact on pidigits for -n=10000 or -n=20000
because the operands are are too small.
