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.

3:ENGINEERING 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, 12.34567E3 means 12.34567×10
3
1:REAL 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.)
2:RECTANGULAR Displays complex numbers in the form: a+bi
3:POLAR Displays complex numbers in the form: re
i
q
1:RECTANGULAR Coordinates are in terms of x, y, and z. For
example, [3,5,2] represents x = 3, y = 5, and
z = 2.
2:CYLINDRICAL Coordinates are in terms of r, q, and z. For
example, [3,∠45,2] represents r = 3, q = 45,
and z = 2.
3:SPHERICAL Coordinates are in terms of r, q, and f. For
example, [3, ∠45, ∠90] represents r = 3,
q = 45, and f =90.
1:OFF Results are displayed in a linear, one-
dimensional form.
For example, p^2, p/2, or ‡((x-3)/x)
2:ON Results are displayed in conventional
mathematical format.
For example, p
