rotate

For each element in v, the bits are shifted left by the number of bits given by the corresponding element in i (subject to usual shift modulo rules described in section 6.3).

template <typename I, detail::enable_if_t<(detail::builtin::is_geninteger<I>::value), int> >
I rotate(I v, I i)

1. For each element in v, the bits are shifted left by the number of bits given by the corresponding element in i (subject to usual shift modulo rules described in section 6.3).
   Parameters:
   • I v
   • I i
