k Inputting a Constant (Value, Calculation Result, Number Sequence) into
a Cell
A constant is something whose value is fixed as soon as you finalize its input. A constant can
be either a numeric value, or a calculation formula (such as 7+3, sin30, A1 × 2, etc.) that does
not have an equal sign (=) in front of it. Inputting sdaw, for example will cause the
value 0.5 (the calculation result) to appear in the cell (when Deg is selected as the Angle unit).
u To input a number sequence automatically based on a function expression
1. Move the cell cursor to the cell where you want number sequence input to start.
• Under initial default settings, automatic input of the number sequence will proceed
downwards from the start cell. You can specify a different direction using the "Move"
setting as described on page 1-38.
2. Press 2(EDIT) 5(SEQ) to display the Sequence screen, and then specify the function
expression and values required to generate the required number sequence.

Input the function expression
Example: a+(X) x+bw
Var Input the variable name used in the function expression input for Expr.
Example: a+(X) w
Start Input the starting value (X
specified by Var.
Example: cw
End Input the ending value (X
specified by Var.
Example: baw
Incre
