The [MODE] key can be used to select the modes described below.

Important!
The following is a general explanation of Scientific Calculator modes. Note that your calculator may not include all of the modes described here.

1) Calculation Modes
Before performing a calculation, you first need to select the appropriate calculation mode.

COMP: Basic arithmetic calculations
(arithmetic operations, trigonometric functions, etc.)

COMPLEX: Complex number calculations

STAT: Statistical calculations

BASE-N: Binary, octal, decimal, hexadecimal number system calculations

MATRIX : Matrix calculations (determinants, etc.)

VECTOR : Vector calculations

EQN : nth degree equations, simultaneous equations

TABLE : Generate a number table based on one or two functions

2) MthIO/LineIO Settings
Specifies the display format.

MthIO-MathO or MthIO displays input and calculation results using the same format as they are written on Paper.



MthIO-LineO displays input the same way as MathO, but calculation results are displayed in linear format.
(ES PLUS Series only)



LineIO causes fractions and other expressions to be displays in a single line.

3) Display Settings
Use these settings to control how calculation results are displayed.
Note that changing the Fix and Sci settings does not affect internal calculation results.

Norm: Exponential display format and cancels the currently configured Fix and Sci settings.

Fix: Specifies a fixed number of digits to the right of the decimal place.

Sci: Specifies a fixed number of significant digits.

4) Angle Unit Setting
(90°=π/2 radians=100 grads)

Deg: Degrees

Rad: Radians

Gra: Grads
