-1 The commit reverted earlier changes in "FastMath.java". [The mixup shows in the other message (part [2/2]) from "commits@".] Moreover, the introduction of "pow(double,int)" could have been done first and separately from the differentiation stuff. Please revert the changes to "FastMath.java". I don't get how this could happen; isn't subversion supposed to detect that the working copy is outdated?
