A Selecting Interest Calculation for a Period

with a Partial Month

performing each type of calculation, first use Configuring

A CMPD Mode Financial Calculation

Variables (VARS)

  Variables 

n

, I, PV, PMT, FV, P/Y, and C/Y are used in

the CMPD Mode.

  The values of CMPD Mode variables are retained even if

you change to another mode. Note, however, that CMPD

Mode variables are also used by other modes, so

performing an input or calculation operation may change

the values assigned to them.

  Though CMPD Mode variables are financial calculation

variables, they are also used by arithmetic and function

operations in the COMP Mode.
