'''Warning:''' Unlike a normal power operation, the signum of the
left operand is always preserved. I.e. DC.kr(-0.5).pow(2) will
not output 0.25 but -0.25. This is to avoid problems with
floating point noise and negative input numbers, so
DC.kr(-0.5).pow(2.001) does not result in a NaN, for example.
