A DESCRIPTION OF THE REQUEST :
It is sufficiently tricky to do modulo arithmetic on negative integers that methods should be provided in the Math class to do this correctly.
JUSTIFICATION :
A common mistake is to do Math.abs(n) % MODULO. If there were methods in the library that would do it right, these bugs could be more easily avoided. I note that BigInteger has a mod() method (presumably for efficiency).
