The function presentvalue() gives the value at period=0 of an ``amount'' given at period=``nperiods''. The interest rate is given by ``rate''.

The present value concept is arguably the most important concept behind the ``Finance'' package. It allows one to properly account for the time value of money.

The Finance[presentvalue] is the appropriate function to calculate the present value of a pure discount bond (zero-level bond).

The command with(Finance,presentvalue) allows the use of the abbreviated form of this command.

Since presentvalue used to be part of the (now deprecated) finance package, for compatibility with older worksheets, this command can also be called using finance[presentvalue]. However, it is recommended that you use the superseding package name, Finance, instead: Finance[presentvalue].

The Finance[presentvalue] command was introduced in Maple 15.
