initializer element IS a compile-time constant

[popog]

Why does one line fail while the other succeeds.

#pragma OPENCL EXTENSION cl_khr_fp64 : enable

constant unsigned const precision = 3;
constant unsigned const preciselyu = 1 << precision;
constant double const preciselyd = (double)(preciselyu);
constant double const ipreciselyd = 1.0 / preciselyd; // FAILS "error: initializer element is not a compile-time constant"
constant double const ipreciselyd = 1.0 / (double)(preciselyu); // WORKS
