I brute force things with a longer series  it is smaller codewise. There is also the conversion to radians involved to disturb the results a bit. Strange that singe precision works, if you don't do the range reduction to the first octant. For me personally, these things are much more important than having 34 digits most of the time. Accuracy over precision, anytime. And of course the venerable 42S gets it right. And Free42, latest version. range reduction to 45° Werner
