All Implemented Interfaces:

Serializable, Comparable<DoubleEvaluator.Style>

Enclosing class:

DoubleEvaluator

public static enum DoubleEvaluator.Style
extends Enum<DoubleEvaluator.Style>

The order or operations (operator precedence) is not clearly defined, especially between the unary minus operator and exponentiation operator (see http://en.wikipedia.org/wiki/Order_of_operations). These constants define the operator precedence styles.

Enum Constant Summary

Enum Constants

Enum Constant and Description
EXCEL The operator precedence used by Excel, or bash shell script language, where the unary minus as a higher precedence than the exponentiation.
STANDARD The most commonly operator precedence, where the unary minus as a lower precedence than the exponentiation.

Enum Constant Detail

STANDARD

public static final DoubleEvaluator.Style STANDARD

The most commonly operator precedence, where the unary minus as a lower precedence than the exponentiation.
With this style, used by Google, Wolfram alpha, and many others, -2^2=-4.

EXCEL

public static final DoubleEvaluator.Style EXCEL

The operator precedence used by Excel, or bash shell script language, where the unary minus as a higher precedence than the exponentiation.
With this style, -2^2=4.

Method Detail

values

public static DoubleEvaluator.Style[] values()

Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:

for (DoubleEvaluator.Style c : DoubleEvaluator.Style.values())
    System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static DoubleEvaluator.Style valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
