Converting to Polar Coordinates (Pol) Pol(X, Y) • • • X: Specifies the rectangular coordinate X value Y: Specifies the rectangular coordinate Y value Calculation result θ is displayed using the range of -180° < θ ≤ 180° Calculation result θ is displayed using the calculator’s default angle unit. Calculation result r is assigned to variable X, while y is assigned to Y. 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.

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 completion of operation 5 [÷R] 3 [STO] [X] assigns the quotient value of 1 to X. [. . . ] Your input exceeds the allowable input range (particularly when using functions). The calculation you are performing contains an illegal mathematical operation (such as division by zero). 84 Action • • Check the input values, reduce the number of digits, and try again. When using independent memory or a variable as the argument of a function, make sure that the memory or variable value is within the allowable range for the function. Stack ERROR Cause • The calculation you are performing has caused the capacity of the numeric stack or the command stack to be exceeded. Action • • Simplify the calculation expression so it does not exceed the capacity of the stack. Try splitting the calculation into two or more parts. Syntax ERROR Cause • There is a problem with the format of the calculation you are performing. Action • Make necessary corrections. Insufficient MEM Error Cause • There is not enough memory to perform your calculation. Action • Narrow the table calculation range by changing the Start, End, and Step values, and try again. Before assuming malfunction of the calculator Perform the following steps whenever an error occurs during a calculation or when calculation are not what you expected. [. . . ]
