A Notes
• These functions can be used in the COMP, SD, and REG Modes.
• Calculation results show the fi rst
r x
• The -value (or

-value (or -value) is assigned to variable Y (page 22). To view the -value (or
display the value assigned to variable Y, as shown in the example.
• The values obtained for
coordinates is within the range –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 (
