A Syntax and Input 

Rectangular-to-Polar Coordinate Conversion (Pol) 

Pol( 

,

)

:  Rectangular coordinate  

-value

:  Rectangular coordinate  

-value 

Polar-to-Rectangular Coordinate Conversion (Rec) 

Rec(

,

)

:  Polar coordinate  

-value

:  Polar coordinate  

-value 

Example 1:  To convert the rectangular coordinates ( 

'

2,

'

2 ) to polar coordinates 

(Angle Unit: Deg) 

1+(Pol) 92)

Example 2:  To convert the polar coordinates (2, 30°) to rectangular coordinates 

(Angle Unit: Deg) 

1-(Rec)2,

30)E

(View the value of  

)

t,(Y)

A Notes 

• These functions can be used in the COMP, SD, and REG Modes. 
• Calculation results show the fi rst  

 value or  

 value only. 

• The  

-value (or  

-value) produced by the calculation is assigned to variable X, while the 

-value (or  

-value) is assigned to variable Y (page 22). To view the  

-value (or  

-value), 

display the value assigned to variable Y, as shown in the example. 

• The values obtained for  

 when converting from rectangular coordinates to polar 

coordinates is within the range –180°<  

< 180°. 

• When executing a coordinate conversion function inside of a calculation expression, the 

calculation is performed using the fi rst value produced by the conversion ( 

-value or  

-

value). 
Example: Pol (
