Note

If you include values or expressions in parentheses (( and )) while using natural display, the height of the parentheses will adjust automatically depending on whether they enclose one line or two lines. Regardless of their height, opening and closing parentheses take up one byte of memory each.

Inputting Calculation Expressions Using Natural Display

1.To input a specific function, perform the operation in the “Key Operation” column of the “Scientific Functions that Support Natural Display” table.

2.At the input fields indicated by , input the required values and expressions.• Use the cursor keys to move between the input fields of the expression.

Example: To input 1 + 2 2 × 3

B

Specify fraction input:

'

Input the numerator:1+2
Move the cursor to the denominator: cInput the denominator: 2*3Execute the calculation: EImportant!

Certain types of expressions can cause the height of a calculation formula to be greater than one display line. The maximum allowable height of a calculation formula is two display screens (31 dots × 2). Further input will become impossible if the height of the calculation you are inputting exceeds the allowable limit.

Nesting of functions and parentheses is allowed. Further input will become impossible if you nest too many functions and/or parentheses. If this happens, divide the calculation into multiple parts and calculate each part separately.
