Bonds106
When entering data for bond calculations, results are calculated based on data entered into
specific memory registers. When pressed, the keys used for these operations:
• store data.
• enter data for variables used during calculations (input only).
• calculate unknown variables based on stored data.
Most of the other keys used in bond calculations allow you to enter data for a variable, but
you cannot solve for that variable. The exception is the
]Û key. This key permits you
to return results for accumulated interest, but you cannot enter data into this key.
Before you perform a bond calculation, be sure to verify the date format is set appropriately
for your problem. The default setting is mm.ddyyyy, but it can be set for dd.mmyyyy. For more
information about entering dates and date formats, see chapter 9, Calendar Formats and
Date Calculations. The range of acceptable dates is October 15, 1582 to December 31, 9999.
Verify that bond day counts (360/365) and annual or semiannual coupon payment schedules
are appropriate for your problem prior to inputting your data.
