Returns the forward-difference quotient
(average rate of change).
Expr1 can be a user-defined function name
(see Func).
When Value is specified, it overrides any
prior variable assignment or any current “|”
substitution for the variable.
Step is the step value. If Step is omitted, it
defaults to 0.001.
Note that the similar function centralDiff()
uses the central-difference quotient.
