octave: libinterp/corefcn/xpow.cc annotate

annotate libinterp/corefcn/xpow.cc @ 29831:ef138252af51

xpow.cc: Use static_cast<int> in a consistent manner for exponent. * xpow.cc (xpow (DiagMatrix, double), xpow (FloatDiagMatrix, float)): Cast exponent to integer just once and use that result (variable bint) in innermost for loop calling std::pow. * xpow.cc (elem_xpow (NDArray, double), elem_xpow (FloatNDArray, float)): Re-write code to test for "xisint (b)" rather than "! xisint (b)" to match stytle of all other functions.
