Constants Statement 

Constants Statement SyntaxThe Fractal Science Kit fractal generator constants statement is 1 of the statements used in the properties section of the program instructions to define the program's Properties. The constants statement is used to define a set of complex constants available to the program instructions. The format of the constants statement is: constants [ <Name> ] { <Name> and each <Identifier> must be a valid identifier. Each <Expression> must be a valid complex expression. The <Expression> may use any of the defined options or enums. OptionArray statements may reference these constants. Option definitions may not use these constants in their enabled expressions, however. Finally, the <Expression> must evaluate to a complex (nonobject) value. The name of the constant is <Name> followed by a period (.) and then the <Identifier>. <Name> is optional when you define the set of constants, and if it is not given, the name of each constant is simply the <Identifier>. Example: option Angle { This example defines a complex constant named Rotation that can be used to rotate a number. Remember that the value of the expression z*Cis(A) is equal to the point z rotated about the origin by A radians if A is a floating point number. Using this fact and the above definitions, we can rotate a point z by Angle degrees about the origin using the expression z*Rotation. Example: constants Math { This example creates several math related constants. These are accessed in your code as Math.TwoPI, Math.Cos0, etc.
