Detailed Description
A class that defines a rounding precision parameterized by a rounding increment to be used when formatting numbers in NumberFormatter.
To create an IncrementPrecision, use one of the factory methods on Precision.

Member Function Documentation
◆ withMinFraction()
| Precision icu::number::IncrementPrecision::withMinFraction | ( | int32_t | minFrac | ) | const |
Specifies the minimum number of fraction digits to render after the decimal separator, padding with zeros if necessary.
By default, no trailing zeros are added.
For example, if the rounding increment is 0.5 and minFrac is 2, then the resulting strings include "0.00", "0.50", "1.00", and "1.50".
Note: In ICU4J, this functionality is accomplished via the scale of the BigDecimal rounding increment.
- Parameters
-
minFrac The minimum number of digits after the decimal separator.
- Returns
- A precision for chaining or passing to the NumberFormatter precision() setter.
