[. . . ] Converting to Rectangular Coordinates (Rec) Rec(r, θ ) • • • r : Specifies r value of polar coordinate θ : Specifies θ value of polar coordinate Input value θ is treated as an angle value, in accordance with the calculator’s default angle unit setting. calculation result x is assigned to variable X , while θ is assigned to Y. If you perform coordinate conversion inside of an expression instead of a stand-alone operation, the calculation is performed using the only first value (either the r-value or the X-value) produced by the conversion. example: Pol ( 2 , 2 ) + 5 = 2 + 5 = 7  (X , Y) = ( 2 + 2 ) → r , θ 34    (Pol)      ( , )         (Pol)      ( , )        (r , θ ) = (2 , 30) → (X , Y)   (Rec)    ( , )  Greatest Common Divisor and Least Common Multiple • • • • • These functions exist in all modes. Greatest Common Divisor (GCD): To calculate the greatest common divisor of two positive integers. Least Common Multiple (LCM): To calculate the least common multiple among two positive integers. The argument value can be either a number and/or expression. π   (LCM)         (, )    (GCD)        (, )    The Integer Function and the Greatest Integer Function • • Int: The integer function extracts the integer part of the value by removing the digits to the right of the decimal point.

At  calculation, only the quotient is stored in the  memory. R is part of a series of multiple statements, only the quotient will be transferred to the next operation.

If one of the following conditions is present when performing an operation with calculation will be treated as a normal division without calculation or display of remainder. When the dividend is greater than 1 ✕ 1010. When the quotient is not a positive value or the remainder is not an entire positive or a positive fraction. If necessary, you can also specify the divisor. "Non simplifiable" appears when the value you specify is invalid as a divisor for simplification. 678 37     Using CALC • You can store a single mathematical expression, with up to 99 steps. Note that the  command can only be used in the COMP Mode. € The  command lets you temporarily store a mathematical expression that you need to perform several times. Once you store an expression, you can recall it, input variables, and calculate quickly. [. . . ] This will cause the calculator to perform a routine that checks whether calculation functions are operating correctly. If the calculator discovers any abnormality, it automatically initializes the calculation mode and clears memory contents. For details about initialized settings, see “Initializing the Calculation Mode and Other Calculator Setup. Replacing the Battery Dim figures on the display of the calculator indicate that battery power is low. [. . . ]
