Inputting and Editing

• You can enter the following expressions for check mode

VERIFY.
A. Equalities or inequalities involving a relational operator.

4 =

; 4 ≠ 3;

π

> 3; 1 + 2 ≤ 5; (3

✕ 6) < (2 + 6) ✕ 2; etc.

B. Equalities or inequalities involving multiple relational operator

1 ≤ 1 < 1 + 1; 3 <

π

< 4; 2

2

= 2 + 2 = 4; 2 + 2 = 4 < 6; 2 + 3

= 5 ≠ 2 + 5 = 8; etc.

• The values and expressions you can input on the display

are the same as those you can input in the COMP Mode.

• The expression entry is up to 99 bytes, including the left,

the right side and the relational operators.

• Pressing the

keys displays a menu of functions.

Press the number key that corresponds to the function you
want to input.

• In the expression with no relational operator, press

,

the system will automatically join “= 0” as the end of the
expression.

• The following operations are not supported:

and multi-statements also cannot be

input with the VERIFY mode.

• The following expression type cause a Syntax ERROR:

A. An expression with no end to the left or right (Example:
= )
B. An expression in which a relational operator is fraction

or function (Example:

, cos (8 • 9))

C. An expression in which relational operators are
surrounded by parentheses. (Example: 8 < (9 < 10))
D. An expression in which there are multiple relational
operators which are not oriented in the same direction
(Example: 5 ≤ 6 ≥ 4)
E. An expression that contains two of the following
relational operators in any combination (Example: 4 < 6 • 8)
F. An expression contains relational operators consecutive
(Example: 5 ≥ > 4)
