public final class ScientificNumberFormatter
extends Object
A formatter that formats numbers in user-friendly scientific notation. ScientificNumberFormatter instances are immutable and thread-safe. Sample code:
ULocale en = new ULocale("en"); ScientificNumberFormatter fmt = ScientificNumberFormatter.getMarkupInstance( en, "<sup>", "</sup>"); // Output: "1.23456×10<sup>-78</sup>" System.out.println(fmt.format(1.23456e-78));
Summary
Inherited methods |
From class java.lang.Object Object | clone() Creates and returns a copy of this object. | boolean | equals(Object obj) Indicates whether some other object is "equal to" this one. | void | finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. | final Class<?> | getClass() Returns the runtime class of this Object. | int | hashCode() Returns a hash code value for the object. | final void | notify() Wakes up a single thread that is waiting on this object's monitor. | final void | notifyAll() Wakes up all threads that are waiting on this object's monitor. | String | toString() Returns a string representation of the object. | final void | wait(long timeoutMillis, int nanos) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait(long timeoutMillis) Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed. | final void | wait() Causes the current thread to wait until it is awakened, typically by being notified or interrupted. | |
Public methods
public String format (Object number)
Formats a number
| Parameters |
number | Object: Can be a double, int, Number or anything that DecimalFormat#format(Object) accepts. |
| Returns |
String | the formatted string. |
getMarkupInstance
public static ScientificNumberFormatter getMarkupInstance (DecimalFormat df, String beginMarkup, String endMarkup)
Gets a ScientificNumberFormatter instance that uses markup for exponents.
| Parameters |
df | DecimalFormat: The DecimalFormat must be configured for scientific notation. Caller may safely change df after this call as this method clones it when creating the ScientificNumberFormatter. |
beginMarkup | String: the markup to start superscript e.g <sup> |
endMarkup | String: the markup to end superscript e.g </sup> |
getMarkupInstance
public static ScientificNumberFormatter getMarkupInstance (ULocale locale, String beginMarkup, String endMarkup)
Gets a ScientificNumberFormatter instance that uses markup for exponents for this locale.
| Parameters |
locale | ULocale: The locale |
beginMarkup | String: the markup to start superscript e.g <sup> |
endMarkup | String: the markup to end superscript e.g </sup> |
getSuperscriptInstance
public static ScientificNumberFormatter getSuperscriptInstance (DecimalFormat df)
Gets a ScientificNumberFormatter instance that uses superscript characters for exponents.
| Parameters |
df | DecimalFormat: The DecimalFormat must be configured for scientific notation. Caller may safely change df after this call as this method clones it when creating the ScientificNumberFormatter. |
getSuperscriptInstance
public static ScientificNumberFormatter getSuperscriptInstance (ULocale locale)
Gets a ScientificNumberFormatter instance that uses superscript characters for exponents for this locale.
| Parameters |
locale | ULocale: The locale |
