Using the Financial Functions
Entering Cash Inflows and Cash Outflows
When using the financial functions, you must enter cash inflows (cash received) as
positive numbers and cash outflows (cash paid) as negative numbers. The financial
functions follow this convention when computing and displaying answers.

Each TVM function takes zero to six arguments. Each argument must be a real
number or a TVM variable. The values that you specify as arguments for these
functions are not stored to the TVM variables.
If you enter less than six arguments, you must enter arguments in the order of the
syntax, up to the last argument you want to enter. The program substitutes a
previously stored TVM variable value for each subsequent unspecified argument.
If you enter any arguments with a TVM function, you must place the argument or
arguments in parentheses. The following examples show some ways to use the
TVM functions.
