Thomas Neidhart commented on MATH-1198:
---------------------------------------
This conversion might also trigger the JIT bug:
{code}
int intVal = (int) x;
{code}
Thus I proposed to do the first check with the unchanged double value.
Afterwards we are quite sure that we are not affected by the bug anymore.
