Pure java implementation of the java.lang.Math class

I just downloaded the openjdk source and came to the realization that nearly all of the java.lang.Math class was implemented in native c/c++ code. I was wondering if there were any implementations that were fully written in java.

Have a look at MicroFloat. It targets J2ME platform and according to the author it implements all methods in java.lang.Math.
