Is this normal or a bug ?

The difference in the assert statement could be because of the 
different float representations used in C++ and D. C++ and D 
might employ different floating-point models, leading to minor 
precision differences in arithmetic operations. To resolve this, 
consider using data types or libraries that ensure consistent 
float representations across both languages.
