Method Details

compare

public static int compare(double d1,
double d2,
double precision)

Compares two numbers within a given precision (number of zeros). Returns -1 if d1 < d2, +1 if d1 > d2, zero otherwise.

Parameters:

d1 -

d2 -

precision -

Returns:

getMultiple

public static int getMultiple(double d1,
double d2)

ceilToOdd

public static int ceilToOdd(double d)

getInstance

public static MguiNumber getInstance(DataType type,
double value)

Returns an instance of an MguiNumber of the specified type and value

Parameters:

type -

value -

Returns:

getInstance

public static MguiNumber getInstance(java.lang.Class<?> clazz,
double value)

Returns an instance of an MguiNumber of the specified class and value. Returns null if instantiation failed.

Parameters:

type -

value -

Returns:

getInstance

public static MguiNumber getInstance(java.lang.String type,
double value)

Returns an instance of an MguiNumber of the specified type and value

Parameters:

type - : Name of MguiNumber subclass

value -

Returns:

getDecimalFormat

public static java.text.DecimalFormat getDecimalFormat(int decimal_places)

getDecimalFormat

public static java.text.DecimalFormat getDecimalFormat(int decimal_places,
boolean dividers)

getPoint2fStr

public static java.lang.String getPoint2fStr(org.jogamp.vecmath.Point2f p,
java.lang.String pattern)

isEven

public static boolean isEven(double value)

getPoint3dStr

public static java.lang.String getPoint3dStr(org.jogamp.vecmath.Point3d p,
java.lang.String pattern)

getDifference

MguiNumber n2)

getNextSquare

public static double getNextSquare(double n)

Returns the next highest square number

getSum

public static double getSum(double[] n)

getReasonableString

public static java.lang.String getReasonableString(double d)

getReasonableFormat

public static java.lang.String getReasonableFormat(double d)

getValueForObject

public static double getValueForObject(java.lang.Object obj)

Determines the numeric value of obj and returns it as a double. obj must be an instance of arNumber, or a Java primitive wrapper (one of Integer, Short, Float, or Double).

If obj does not satisfy these criteria, Double.NaN is returned.

Parameters:

obj -

Returns:

isNumeric

public static boolean isNumeric(java.lang.Object obj)

Determines whether obj is numeric; i.e., an instance of MguiNumber (except arBoolean), or a Java primitive wrapper (one of Integer, Short, Float, or Double).

Parameters:

obj -

Returns:

true if numeric, false otherwise.
