Cases when Remainder Division becomes

Non-remainder Division

If either of the following conditions exists when you perform a remainder

division operation, the calculation will be treated as normal (non-remainder)

division.

•

When either the dividend or the divisor is a very large value

Example: 20000000000 u 17 =

→ Calculated as: 20000000000 ÷ 17

•

When the quotient is not a positive integer, or if the remainder is not a

positive integer or positive fractional value

Example: - 5 u 2 = → Calculated as: –5 ÷ 2

Function Calculations

For actual operations using each function, see the "Examples" section

following the list below.

π π : π is displayed as 3.141592654, but π = 3.14159265358980 is used for

internal calculations. See

: Exponential function. See

^, ),

−1

: Powers, square root, and reciprocals. See

Note: The following functions cannot be input in consecutive sequence:

. If you input 2ww, for example, the final w will be ignored. To

Ran# : Generates a 3-digit pseudo random number that is less than 1. The

result is displayed as a fraction when MathO is selected. See

RanInt# : For input of the function of the form RanInt#(

a random integer within the range of

Rnd : The argument of this function is made a decimal value and then

rounded in accordance with the current number of display digits setting

(Norm or Fix). With Norm 1 or Norm 2, the argument is rounded off to 10

digits. With Fix, the argument is rounded off to the specified digit. When Fix

3 is the display digits setting, for example, the result of 10 ÷ 3 is displayed

as 3.333, while the calculator maintains a value of 3.33333333333333 (15

digits) internally for calculation. In the case of Rnd(10÷3) = 3.333 (with Fix

3), both the displayed value and the calculator's internal value become

3.333. Because of this a series of calculations will produce different results

depending on whether Rnd is used (Rnd(10÷3) × 3 = 9.999) or not used (10

÷ 3 × 3 = 10.000). See

Simp : This function simplifies a fraction using the least divisor. You also

can specify the divisor, if you want. An error is displayed if a fraction cannot

be reduced.

Note : This function is disabled when "Auto" is selected for the Simp setting

on the setup menu. See

Note: Using functions can slow down a calculation, which may delay display

of the result. Do not perform any subsequent operation while waiting for the

calculation result to appear. To interrupt an ongoing calculation before its

result appears, press A.
