Notes
• The examples on the transparency masters
assume all default settings.
• Press p $ $ < to return to
standard notation (floating decimal).
• The decimal mode setting affects most
decimal results and the mantissa of
scientific and engineering notation results.
• The TI-30XS MultiView™ calculator
automatically rounds the result to the
number of decimal places selected. For
example, when the decimal is set to 2 places,
0.147 becomes 0.15 when you press <. The
TI-30XS MultiView calculator also rounds or
pads resulting values with trailing zeros to fit
the selected setting. For example, when the
decimal is set to 5 places, 0.147 becomes
0.14700 when you press <.
• Resetting the calculator clears the decimal
setting and resets to the default, FLOAT.
• The decimal setting does not affect the
internal precision of results. It affects only
the way results are displayed.
