1MthIO 2LineIO
Natural Display (MthIO) causes fractions,
irrational numbers, and other expressions to be
displayed as they are written on paper.
MthIO: Selects MathO or LineO. MathO displays input and calculation results
using the same format as they are written on paper. LineO displays input the
same way as MathO, but calculation results are displayed in linear format.
Linear Display (LineIO) causes fractions and
other expressions to be displayed in a single
line.
Note: • The calculator switches to Linear Display automatically whenever you
enter the STAT, BASE-N, MATRIX, or VECTOR Mode. • In this manual, the
B symbol next to a sample operation indicates Natural Display (MathO),
while the b symbol indicates Linear Display.
3Deg 4Rad 5Gra
unit for value input and calculation result display.
Note: In this manual, the v symbol next to a sample operation indicates
degrees, while the V symbol indicates radians.

calculation result.
Fix: The value you specify (from 0 to 9) controls the number of decimal
places for displayed calculation results. Calculation results are rounded off
to the specified digit before being displayed.
Example: b 100 ÷ 7 = 14.286 (Fix 3)
Sci: The value you specify (from 1 to 10) controls the number of significant
digits for displayed calculation results. Calculation results are rounded off to
the specified digit before being displayed.
Example: b 1 ÷ 7 = 1.4286 × 10
Norm: Selecting one of the two available settings (Norm 1, Norm 2)
determines the range in which results will be displayed in non-exponential
format. Outside the specified range, results are displayed using exponential
format.
