ScientificNumberFormatter
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));

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 |
