withSignificantDigits
public Precision withSignificantDigits(int minSignificantDigits, int maxSignificantDigits, NumberFormatter.RoundingPriority priority) Override maximum fraction digits with maximum significant digits depending on the magnitude of the number. See UNumberRoundingPriority.- Parameters:
minSignificantDigits
- Pad trailing zeros to achieve this minimum number of significant digits.maxSignificantDigits
- Round the number to achieve this maximum number of significant digits.priority
- How to disambiguate between fraction digits and significant digits.- Returns:
- A precision for chaining or passing to the NumberFormatter precision() setter.
-
withMinDigits
Ensure that no less than this number of significant digits are retained when rounding according to fraction rules.For example, with integer rounding, the number 3.141 becomes "3". However, with minimum figures set to 2, 3.141 becomes "3.1" instead.
This setting does not affect the number of trailing zeros. For example, 3.01 would print as "3", not "3.0".
This is equivalent to
withSignificantDigits(1, minSignificantDigits, RELAXED)
.- Parameters:
minSignificantDigits
- The number of significant figures to guarantee.- Returns:
- A Precision for chaining or passing to the NumberFormatter rounding() setter.
- Throws:
IllegalArgumentException
- if the input number is too big or smaller than 1.- See Also:
-
withMaxDigits
Ensure that no more than this number of significant digits are retained when rounding according to fraction rules.For example, with integer rounding, the number 123.4 becomes "123". However, with maximum figures set to 2, 123.4 becomes "120" instead.
This setting does not affect the number of trailing zeros. For example, with fixed fraction of 2, 123.4 would become "120.00".
This is equivalent to
withSignificantDigits(1, maxSignificantDigits, STRICT)
.- Parameters:
maxSignificantDigits
- Round the number to no more than this number of significant figures.- Returns:
- A Precision for chaining or passing to the NumberFormatter rounding() setter.
- Throws:
IllegalArgumentException
- if the input number is too big or smaller than 1.- See Also:
