Calculation Modes
The Main application has a number of different modes, as described under “Using Main
Application Modes” on page 2-1-4. The display format of calculation results depends on the
currently selected Main application mode. This section tells you which mode you need to use
for each type of calculation, and explains the differences between the calculation results
produced by each mode.
• All of the following calculation examples are shown using the Algebra mode only.
k Standard Mode and Decimal Mode
The Standard mode displays calculation results in mathematical expression format whenever
possible, while the decimal mode converts calculation results to a decimal form. When the
Decimal mode is selected, you can control the use of exponential notation with the [Display]
setting on the Basic Format dialog box (page 13-3-1).
