Angle
Specifies the units in which angle values are interpreted and displayed in trig functions
and polar/rectangular conversions.
1:RADIAN
2:DEGREE
3:GRADIAN
Exponential Format
Specifies which notation format should be used. These formats affect only how an
answer is displayed; you can enter a number in any format. Numeric answers can be
displayed with up to 12 digits and a 3-digit exponent.
1:NORMAL
2:SCIENTIFIC
3:ENGINEERING
Note: If you select NORMAL, but the answer cannot be displayed in the number of digits
selected by Display Digits, the TI-89 Titanium / Voyage™ 200 displays the answer in
SCIENTIFIC notation. If Display Digits = FLOAT, scientific notation will be used for
exponents of 12 or more and exponents of -4 or less.
Complex Format
Specifies whether complex results are displayed and, if so, their format.
1:REAL
2:RECTANGULAR Displays complex numbers in the form: a+bi
3:POLAR
Appendix B: Technical Reference
If the integer part has more than the selected
number of digits, the result is rounded and
displayed in scientific notation.
For example, in FLOAT 4:
12345. is shown as 1.235E4
Expresses numbers in standard format. For
example, 12345.67
Expresses numbers in two parts:
•
The significant digits display with one digit to the
left of the decimal.
The power of 10 displays to the right of
•
For example, 1.234567
Similar to scientific notation. However:
•
The number may have one, two, or three digits
before the decimal.
•
The power-of-10 exponent is a multiple of three.
For example, 12.34567
Does not display complex results. (If a result is
a complex number and the input does not
contain the complex unit i, an error message is
displayed.)
