Hi,
attached is a new test for the cbrt method of StrictMath.
This file should probably be placed as
gnu/testlet/java/lang/StrictMath/cbrt.java
which I can't add since I don't have write access to the cvs, hence this
is not a proper patch, just the file, sorry.
Please comment and/or commit.
Thanks,
Carsten
