class ScientificNumberFormatter
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
| Public methods |
| String! | Formats a number |
| static ScientificNumberFormatter! | Gets a ScientificNumberFormatter instance that uses markup for exponents. |
| static ScientificNumberFormatter! | Gets a ScientificNumberFormatter instance that uses markup for exponents for this locale. |
| static ScientificNumberFormatter! | Gets a ScientificNumberFormatter instance that uses superscript characters for exponents. |
| static ScientificNumberFormatter! | Gets a ScientificNumberFormatter instance that uses superscript characters for exponents for this locale. |
Public methods
fun format(number: Any!): String!
Formats a number
| Parameters |
number | Any!: Can be a double, int, Number or anything that DecimalFormat#format(Object) accepts. |
| Return |
String! | the formatted string. |
getMarkupInstance
static fun getMarkupInstance(
df: DecimalFormat!,
beginMarkup: String!,
endMarkup: String!
): ScientificNumberFormatter!
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
static fun getMarkupInstance(
locale: ULocale!,
beginMarkup: String!,
endMarkup: String!
): ScientificNumberFormatter!
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
static fun getSuperscriptInstance(df: DecimalFormat!): ScientificNumberFormatter!
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
static fun getSuperscriptInstance(locale: ULocale!): ScientificNumberFormatter!
Gets a ScientificNumberFormatter instance that uses superscript characters for exponents for this locale.
| Parameters |
locale | ULocale!: The locale |
