g++ -v Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/c++/4.2.1 Apple LLVM version 6.1.0 (clang-602.0.53) (based on LLVM 3.6.0svn) Target: x86_64-apple-darwin14.5.0 Thread model: posix I believe that explicitly casting one of the arguments to either float or double will resolve it. However, at present it looks like it is performing integer division, so perhaps Matias should recommend a solution. Hi. It's a bug, actualPower should be a double. John please try this patch, I can't reproduce the problem on my platform. Created attachment 2125 [details]

Great! I attach a patch for this and for the other example where pow is used. Can you please test the changes? Thanks. Created attachment 2126 [details]

power adaptation interference patch
This patch is for the other example where the function pow is used.
