MOD(I, J) is the remainder when I is divided by J, like I % J in C.
It is defined at the top of p. 15-23 of the standard, and is technically
defined as I - INT(I/J)*J, which unfortunately is not an optimal choice
for negative numbers.

One of the advantages of having a standard is that questions can be
correctly answered on the basis of facat.  Dan, are you listening?
