Pol(X, Y)　X: Specifies the rectangular coordinate X value

Pol(X, Y)　Y: Specifies the rectangular coordinate Y value

Calculation result θ is displayed in the range of -180° < θ < 180°.

Calculation result θ is displayed using the calculator’s angle unit.

Calculation result r is assigned to variable X, while θ is assigned to Y.

Rec(r, θ)　r : Specifies the polar coordinate r value

Rec(r, θ)　θ : Specifies the polar coordinate θ value

Input value θ is treated as an angle value, in accordance with the calculator’s angle unit setting.

Calculation result x is assigned to variable X, while y is assigned to Y.

If you perform coordinate conversion inside of an expression instead of a stand-alone operation, the calculation is performed using only the first value (either the r-value or the X-value) produced by the conversion.
Example: Pol (√2, √2) + 5 = 2 + 5 = 7

Example 1: (X, Y) = (√2, √2) → (r, θ) (Angle Unit: Degree)
