dmd generates SSE instructions for floating point math.
FloatingPointControl only minds the control register for the FPU. But
SSE instructions are not affected by that. SSE has a separate control
register: MXCSR.

Thx for the investigation!
Here is the code for FloatingPointControl

Other code (enableExceptions / disableExceptions) seems to have two code

the Floating Point unit is set to Round Up.
Here is some C++ code:

int main(int, char**) {
std::fesetround(FE_UPWARD);
printf("%.32g\n", std::numeric_limits::denorm_min() +
