Modify Function
14
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function (@ n), the internal
value is converted to match that of the display, so that the
displayed value can be used without change in subsequent
operations.
• When using the WriteView editor, if the calculation result is
displayed using fractions or irrational numbers, press U
to convert it to decimal form first.
STATISTICAL CALCULATIONS

• Within the ranges specified, this calculator is accurate to
±1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same
for y x, xr, n!, e x, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• Calculation ranges
±10−99 to ±9.999999999 × 1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10−99, the value is
considered to be 0 in calculations and in the display.

Modify Function
14
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function (@ n), the internal
value is converted to match that of the display, so that the
displayed value can be used without change in subsequent
operations.
• When using the WriteView editor, if the calculation result is
displayed using fractions or irrational numbers, press U
to convert it to decimal form first.
STATISTICAL CALCULATIONS

• Within the ranges specified, this calculator is accurate to
±1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same
for y x, xr, n!, e x, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• Calculation ranges
±10−99 to ±9.999999999 × 1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10−99, the value is
considered to be 0 in calculations and in the display.

Modify Function
14
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function (@ n), the internal
value is converted to match that of the display, so that the
displayed value can be used without change in subsequent
operations.
• When using the WriteView editor, if the calculation result is
displayed using fractions or irrational numbers, press U
to convert it to decimal form first.
STATISTICAL CALCULATIONS

• Within the ranges specified, this calculator is accurate to
±1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same
for y x, xr, n!, e x, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• Calculation ranges
±10−99 to ±9.999999999 × 1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10−99, the value is
considered to be 0 in calculations and in the display.

Modify Function
14
Decimal calculation results are internally obtained in scientific
notation, with up to 14 digits in the mantissa. However, since
calculation results are displayed in the form designated by the
display notation and the number of decimal places indicated,
the internal calculation result may differ from that shown in the
display. By using the modify function (@ n), the internal
value is converted to match that of the display, so that the
displayed value can be used without change in subsequent
operations.
• When using the WriteView editor, if the calculation result is
displayed using fractions or irrational numbers, press U
to convert it to decimal form first.
STATISTICAL CALCULATIONS

Single-variable statistical calculation
Statistics of ①.
Linear regression calculation
Statistics of ① and ②. In addition, the estimate of y for a
given x (estimate y´) and the estimate of x for a given y
(estimate x´).
Quadratic regression calculation
Statistics of ① and ②, and coefficients a, b, c in the quadratic
regression formula ( y = a + bx + cx 2). (For quadratic
regression calculations, no correlation coefficient (r) can be
obtained.) When there are two x´ values, each value will be

• Within the ranges specified, this calculator is accurate to
±1 of the 10th digit of the mantissa. However, a calculation
error increases in continuous calculations due to
accumulation of each calculation error. (This is the same
for y x, xr, n!, e x, ln, etc., where continuous calculations
are performed internally.)
Additionally, a calculation error will accumulate and
become larger in the vicinity of inflection points and
singular points of functions.
• Calculation ranges
±10−99 to ±9.999999999 × 1099 and 0.
If the absolute value of an entry or a final or intermediate
result of a calculation is less than 10−99, the value is
considered to be 0 in calculations and in the display.
