Summary

Public methods

ScientificNotation withExponentSignDisplay(NumberFormatter.SignDisplay exponentSignDisplay)

Sets whether to show the sign on positive and negative exponents in scientific notation.

ScientificNotation withMinExponentDigits(int minExponentDigits)

Sets the minimum number of digits to show in the exponent of scientific notation, padding with zeros if necessary.

withExponentSignDisplay

Added in API level 30
public ScientificNotation withExponentSignDisplay (NumberFormatter.SignDisplay exponentSignDisplay)

Sets whether to show the sign on positive and negative exponents in scientific notation. The default is AUTO, showing the minus sign but not the plus sign.

For example, with exponentSignDisplay=ALWAYS, the number 123 will be printed as "1.23E+2" in en-US instead of the default "1.23E2".

Parameters
exponentSignDisplay NumberFormatter.SignDisplay: The strategy for displaying the sign in the exponent.

Returns
ScientificNotation A ScientificNotation, for chaining.

withMinExponentDigits

Added in API level 30
public ScientificNotation withMinExponentDigits (int minExponentDigits)

Sets the minimum number of digits to show in the exponent of scientific notation, padding with zeros if necessary. Useful for fixed-width display.

For example, with minExponentDigits=2, the number 123 will be printed as "1.23E02" in en-US instead of the default "1.23E2".

Parameters
minExponentDigits int: The minimum number of digits to show in the exponent.

Returns
ScientificNotation A ScientificNotation, for chaining.

Throws
IllegalArgumentException if minExponentDigits is too big or smaller than 1
