[jira] Updated: (HARMONY-551) [classlib][java.math] performance
improvement for java.math package

[ http://issues.apache.org/jira/browse/HARMONY-551?page=all ]
Vladimir Strigun updated HARMONY-551:
-------------------------------------
Attachment: mathPerformanceTests.zip
Rough micro bench for BigInteger and BigDecimal classes. The suite is intended for comparison of performance between current implemenation of math and fixed one.
The following methods can be tested for BigInteger:
- add
- divide
- gcd
- multiply
- pow
- subtract
- toString
for BigDecimal:
- add
- divide
- multiply
- subtract
- negate
- setScale
- toString
Please compile it before use. To run tests, please use MathTests launcher. All test methods will execute for 20 seconds and as a result you will get operation/seconds value.
