Computational Accuracy
To maximize accuracy, the TI -86 carries more digits internally than it displays. Values are
stored in memory using up to 14 digits with a 3-digit exponent.
♦
You can store values up to 12 digits long to most window variables. To xScl , yScl , tStep ,
and q Step , you can store values up to 14 digits long.
♦
When a value is displayed, the displayed value is rounded as specified by the mode
setting (Chapter 1), with a maximum of 12 digits and a 3-digit exponent.
♦
Chapter 4 describes calculations in hexadecimal, octal, and binary number bases.
