Fair enough, so with 64 bit floats you have no right to expect an accurate answer for sin(2^90). However, you DO have a right to expect an answer in the range [-1,+1] rather than the 1.2e+27 that Richard quoted. I see no words in the description of -funsafe-math-optimizations to lead me to expect such a result. paul
