What should I note when performing integral calculations?
Integral calculations, depending on the integrands and subintervals included, require longer calculation time. During calculation, “Calculating!” will be displayed. To cancel calculation, press ª. In addition, please note that there will be greater integral errors when there are large fluctuations in the integral values during minute shifting of the integral range and for periodic functions, etc., where positive and negative integral values exist depending on the interval. For the former case, divide integral intervals as small as possible. For the latter case, separate the positive and negative values. Following these tips will allow results of calculations with greater accuracy and will also shorten the calculation time.

What is the modify function?
In this calculator, all calculation results are internally obtained in scientific notation with up to 12 digits for 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, the internal value is converted to match that of the display, so that the displayed value can be used without change in subsequent operations.
How does simulation calculation work?
If you have to find a value consecutively using the same formula, such as plotting a curve line for 2×2 + 1, or finding the variable for 2x + 2y =14, once you enter the equation, all you have to do is to specify the value for the variable in the formula.

- an attempt is made to take the square root of a negative number.
- no solution exists in the quadratic regression calculation.
What should I note about normal probability calculations?
P(t), Q(t), and R(t) will always take positive values, even when t<0, because these functions follow the same principle used when solving for an area. Values for P(t), Q(t), and R(t) are given to six decimal places.

What is an equation too long error (Error 4)?
The equation exceeded its maximum input buffer (142 characters). An equation must be shorter than 142 characters.
What is an equation recall error (Error 5)?
The stored equation contains a function not available in the mode used to recall the equation. For example, if a numerical value with numbers other than 0 and 1 is stored as a decimal, etc., it cannot be recalled when the calculator is set to binary.
What is the calculator’s accuracy range?
Within the ranges specified, this calculator is accurate to ±1 in the least significant digit of the mantissa. When performing continuous calculations (including chain calculations), errors accumulate leading to reduced accuracy.
What is the calculation range?
Calculation ranges ±10-99 – ±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.
