Detailed Description
A class that defines the scientific notation style to be used when formatting numbers in NumberFormatter.
To create a ScientificNotation, use one of the factory methods in Notation.

Member Function Documentation
◆ withExponentSignDisplay()
| ScientificNotation icu::number::ScientificNotation::withExponentSignDisplay | ( | UNumberSignDisplay | exponentSignDisplay | ) | const |
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 The strategy for displaying the sign in the exponent.
- Returns
- A ScientificNotation, for chaining.

◆ withMinExponentDigits()
| ScientificNotation icu::number::ScientificNotation::withMinExponentDigits | ( | int32_t | minExponentDigits | ) | const |
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 The minimum number of digits to show in the exponent.
- Returns
- A ScientificNotation, for chaining.
