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.

> Patch (to follow) simplifies the exp function and hopefully avoids the Java 1.5 JIT bug as well.
