Uses of RoundingMode in java.math

Methods in java.math that return RoundingMode

RoundingMode MathContext.getRoundingMode()
          Returns the roundingMode setting.

static RoundingMode RoundingMode.valueOf(int rm)
          Returns the RoundingMode object corresponding to a legacy integer rounding mode constant in BigDecimal.

static RoundingMode RoundingMode.valueOf(String name)
          Returns the enum constant of this type with the specified name.

static RoundingMode[] RoundingMode.values()
          Returns an array containing the constants of this enum type, in the order they are declared.

Methods in java.math that return RoundingMode
`RoundingMode`	`MathContext.getRoundingMode()` Returns the roundingMode setting.
`static RoundingMode`	`RoundingMode.valueOf(int rm)` Returns the `RoundingMode` object corresponding to a legacy integer rounding mode constant in `BigDecimal`.
`static RoundingMode`	`RoundingMode.valueOf(String name)` Returns the enum constant of this type with the specified name.
`static RoundingMode[]`	`RoundingMode.values()` Returns an array containing the constants of this enum type, in the order they are declared.

Methods in java.math with parameters of type RoundingMode

BigDecimal BigDecimal.divide(BigDecimal divisor, int scale, RoundingMode roundingMode)
          Returns a BigDecimal whose value is (this / divisor), and whose scale is as specified.

BigDecimal BigDecimal.divide(BigDecimal divisor, RoundingMode roundingMode)
          Returns a BigDecimal whose value is (this / divisor), and whose scale is this.scale().

BigDecimal BigDecimal.setScale(int newScale, RoundingMode roundingMode)
          Returns a BigDecimal whose scale is the specified value, and whose unscaled value is determined by multiplying or dividing this BigDecimal's unscaled value by the appropriate power of ten to maintain its overall value.

Methods in java.math with parameters of type RoundingMode
`BigDecimal`	`BigDecimal.divide(BigDecimal divisor, int scale, RoundingMode roundingMode)` Returns a `BigDecimal` whose value is `(this / divisor)`, and whose scale is as specified.
`BigDecimal`	`BigDecimal.divide(BigDecimal divisor, RoundingMode roundingMode)` Returns a `BigDecimal` whose value is `(this / divisor)`, and whose scale is `this.scale()`.
`BigDecimal`	`BigDecimal.setScale(int newScale, RoundingMode roundingMode)` Returns a `BigDecimal` whose scale is the specified value, and whose unscaled value is determined by multiplying or dividing this `BigDecimal`'s unscaled value by the appropriate power of ten to maintain its overall value.

Constructors in java.math with parameters of type RoundingMode

MathContext(int setPrecision, RoundingMode setRoundingMode)
Constructs a new MathContext with a specified precision and rounding mode.

Constructors in java.math with parameters of type RoundingMode
`MathContext(int setPrecision, RoundingMode setRoundingMode)` Constructs a new `MathContext` with a specified precision and rounding mode.
