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 "with" 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.

Amortization function that calculates schedule balance after a
specified payment.

NPmt specifies the payment number after which you want the data
calculated.

of TVM arguments, page 107.
If you omit Pmt, it defaults to
•
Pmt=tvmPmt(N,I,PV,FV,PpY,CpY,PmtAt).
If you omit FV, it defaults to FV=0.
•
The defaults for PpY, CpY, and PmtAt are the same as for the
•
TVM functions.
roundValue specifies the number of decimal places for rounding.
Default=2.
bal(NPmt,amortTable) calculates the balance after payment number
NPmt, based on amortization table amortTable. The amortTable
argument must be a matrix in the form described under amortTbl(),
page 6.
