Method Summary

double	cost() cost() should be changed to return a float, and should be renamed to costToExecute() cost of EXECUTING this CS, not including any CSs it executes recursively.
double	DForProxy() Execute this CS and cast to double.
static double	fastApproximateCos(double angle) cosine
static double	fastApproximateSin(double angle) Uses a linear interpolation between 2 values in a table of precomputed sines.
static double	fastApproximateTan(double angle) tangent.
java.lang.String	keyword() For the CodeSimian language as a String. CodeSimian language keyword, like "+" "*" "max" ">" etc. Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add. Some CSs might never be intended to be used in the language by their keyword. The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
double	maxD() sine ranges from -1 to 1
double	minD() sine ranges from -1 to 1
static double[]	sinTable(int arraySize, double circleFraction) Returns a new table containing values of sine for many angles.
static double[]	staticSinTable(int arraySize, double circleFraction) Creates a new static sine table for Sin.java and sets other variables related to it

Constructor Detail

Sine

public Sine()

Method Detail

keyword

public java.lang.String keyword()

Description copied from class: DefaultCS

For the CodeSimian language as a String.
CodeSimian language keyword, like "+" "*" "max" ">" etc.

Override this function if you want to specify a keyword other than how I derive them from the class name, like + for Add.

Some CSs might never be intended to be used in the language by their keyword.
The best example (4/05) is Num, because it is used in the language like "3.4" instead of "num()".
Default: Returns class name, minus package name (and its dots), and change the first letter to lowercase.

For example, CS.MaxParams does not override keyword(), which returns "maxP".

Overrides:

keyword in class DefaultCS

See Also:

CS.parent(), CS.newInstance(), CS.name()

DForProxy

public double DForProxy()

Description copied from class: CS

Execute this CS and cast to double.

D() and DForProxy() are the 2 most important functions in CS. They execute this CS. All other execute functions, by default, return DForProxy cast to their own type.

For example, J() calls the proxy which calls JForProxy() which calls DForProxy(). D() calls the proxy which calls DForProxy().

By default, all other primitive EXECUTE functions defer to D.
Functions that EXECUTE this CS: L(Class) L(int,Class,int) Z() B() C() S() I() J() F() D() V()

Specified by:

DForProxy in class DefaultCS

cost

public double cost()

Description copied from class: CS

cost() should be changed to return a float, and should be renamed to costToExecute()

cost of EXECUTING this CS, not including any CSs it executes recursively. The INTERNAL cost.

One unit of myFuel() costs cost() units of fuel(). Beware of CSs that counterfeit fuel.

Returns 1 by default.

Overrides:

cost in class CS

minD

public double minD()

sine ranges from -1 to 1

Overrides:

minD in class CS

maxD

public double maxD()

sine ranges from -1 to 1

Overrides:

maxD in class CS

fastApproximateSin

public static double fastApproximateSin(double angle)

Uses a linear interpolation between 2 values in a table of precomputed sines. Faster than Math.sin(double). Doubles take twice as long to use, and that function probably goes through many cycles of multiplying doubles to converge on the answer. == and < are faster than multiplies.

fastApproximateCos

public static final double fastApproximateCos(double angle)

cosine

fastApproximateTan

public static final double fastApproximateTan(double angle)

tangent. Instead of returning infinity (at 90 and 270 degrees), returns 0.

staticSinTable

public static double[] staticSinTable(int arraySize,
                                      double circleFraction)

Creates a new static sine table for Sin.java and sets other variables related to it

sinTable

public static double[] sinTable(int arraySize,
                                double circleFraction)

Returns a new table containing values of sine for many angles. The first index is sine(0). The last is sine(2*pi*circleFraction)

Parameters:

arraySize - size of returned double array

circleFraction - range 0-1. the fraction of sine values (range of approximate values) to return. A sine graph has 3 lines of symmetry. As little as 1/8 of all sine values can be used to calculate any sine.
