Hi Rahul, I think a Xdoc format guide file is great, but i can not find any very convenient XDoc file creation tool, can you give me some recommendation or suggestion about XDoc tool ? Which tool do you use? Thank You. -Gui Xun Long On 6/6/10, Rahul Akolkar rahul.akol...@gmail.com wrote: Thanks

[math] elementary functions.

2010-06-08 Thread Bill Rossi
Greetings, I have developed over the past year a set of elementary functions similar to those in java.lang.Math, but with the following characteristics: * Higher performance. * Better accuracy. Results are accurate to slightly more that +/- 0.5 ULP. * Pure Java. The standard Math class is

I've looked at StrictMath, generally Math appears to delegates to StrictMath. StrictMath is implemented by the C fdlibm library. This is what I've implemented to date, the code will compile and run on JDK 1.4 and later. It may work on older JDKs, but I don't have them available for testing.

[GSoC] Sandbox project websites

I think its reasonable to get (sandbox) websites posted for the GSoC projects -- website presence can help draw interest. So, for this year, one would have the sites here: http://commons.apache.org/sandbox/gsoc/2010/scxml-eclipse http://commons.apache.org/sandbox/gsoc/2010/scxml-js WDYT?
