Alex, can you give an example, please?

Feature #6973: Add an #integral? method to Numeric to test for whole-number values

Numeric#integer? checks whether an instance is an Integer.  It is often useful to check whether the value of a non-Integer variable is actually a whole number, and the #integer? method doesn't help here.

This patch adds Numeric#integral?, which performs this check.
