The User Guide says:
"When a division operation is performed between two integers, the
result will be an integer."
http://jakarta.apache.org/velocity/user-guide.html#Math
The MathUtils#divide javadoc says:
"Integer-types will be returned as Integer-type if and only if the
modulo of the two numbers is 0."
http://svn.apache.org/repos/asf/jakarta/velocity/trunk/src/java/org/apache/velocity/runtime/parser/node/MathUtils.java
They can't both be right. If you consider backward compatibility, the
user guide should be correct. But my mind says the javadoc is more
convenient... Will?

For now, you can use the MathTool.

Which, I guess, makes a good reason for the user guide to be right.
