ApproximationCircle
Gets the approximate circle.
Format
ApproximationCircle <count>, <x()>, <y()>, <centerX>, <centerY>, <radius>
Parameter
Return value
None.
Description
Gets the approximate circle from the specified number of points, whose coordinates are specified in the <x()>
and <y()> parameters, in the <count> parameter. In the <centerX> and <centerY> parameters, respectively
specify the variables that will hold the center X coordinate and center Y coordinate of the approximate circle
gotten. In the <radius> parameter, specify the variable that will hold the radius of the circle gotten.
In the <count> parameter, specify an integer value of at least 3.
In the <x()> parameter and <y()> parameter, respectively specify a 1D integer array variable or double
precision real number array variable, where a number of coordinate values greater than or equal to the
number specified in the <count> parameter are stored, without adding element numbers but adding () to the
variables.
If an incorrect data type is specified for a parameter, a "Type mismatch" error will occur.
If a non-existent number, numerical value, or combination of data types or values is specified for a parameter,
an "Illegal function call" error will occur.
If the format is written incorrectly, such as writing the macro function name incorrectly, omitting a comma, or
omitting a half-width space, a "Syntax error" error will occur.
