Additional Constructor Summary
def this (bigDecimal : java.math.BigDecimal) : BigDecimal
Method Summary
def * (that : BigDecimal) : BigDecimal
Multiplication of BigDecimals
def + (that : BigDecimal) : BigDecimal
Addition of BigDecimals
def - (that : BigDecimal) : BigDecimal
Subtraction of BigDecimals
def / (that : BigDecimal) : BigDecimal
Division of BigDecimals
def /% (that : BigDecimal) : (BigDecimal, BigDecimal)
Division and Remainder - returns tuple containing the result of divideToIntegralValue and the remainder.
def < (that : BigDecimal) : Boolean
Less-than of BigDecimals
def <= (that : BigDecimal) : Boolean
Less-than-or-equals comparison of BigDecimals
def > (that : BigDecimal) : Boolean
Greater-than comparison of BigDecimals
def >= (that : BigDecimal) : Boolean
Greater-than-or-equals comparison of BigDecimals
def abs : BigDecimal
Returns the absolute value of this BigDecimal
def apply (mc : java.math.MathContext) : BigDecimal
Returns a new BigDecimal based on the supplied MathContext.
override def byteValue : Byte
Converts this BigDecimal to a byte. If the BigDecimal is too big to fit in a byte, only the low-order 8 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.
def charValue : Char
Converts this BigDecimal to a char. If the BigDecimal is too big to fit in a char, only the low-order 16 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value and that it always returns a positive result.
def compare (that : BigDecimal) : Int
Compares this BigDecimal with the specified BigDecimal
def doubleValue : Double
Converts this BigDecimal to a Double. if this BigDecimal has too great a magnitude to represent as a double, it will be converted to Double.NEGATIVE_INFINITY or Double.POSITIVE_INFINITY as appropriate.
override def equals (that : Any) : Boolean
Compares this BigDecimal with the specified value for equality. Will only claim equality with scala.BigDecimal and java.math.BigDecimal.
def equals (that : BigDecimal) : Boolean
Compares this BigDecimal with the specified BigDecimal for equality.
def floatValue : Float
Converts this BigDecimal to a float. if this BigDecimal has too great a magnitude to represent as a float, it will be converted to Float.NEGATIVE_INFINITY or Float.POSITIVE_INFINITY as appropriate.
override def hashCode : Int
Returns the hash code for this BigDecimal. Note that this does not use the underlying java object's hashCode because we compare BigDecimals with compareTo which deems 2 == 2.00, whereas in java these are unequal with unequal hashCodes.
def intValue : Int
Converts this BigDecimal to an int. If the BigDecimal is too big to fit in a char, only the low-order 32 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.
protected override def isWhole : Boolean
def longValue : Long
Converts this BigDecimal to a Long. If the BigDecimal is too big to fit in a char, only the low-order 64 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.
def max (that : BigDecimal) : BigDecimal
Returns the maximum of this and that
def min (that : BigDecimal) : BigDecimal
Returns the minimum of this and that
def pow (n : Int) : BigDecimal
Returns a BigDecimal whose value is this* n.
def precision : Int
Returns the precision of this BigDecimal.
def quot (that : BigDecimal) : BigDecimal
Divide to Integral value.
def remainder (that : BigDecimal) : BigDecimal
Remainder after dividing this by that.
def round (mc : java.math.MathContext) : BigDecimal
Returns a BigDecimal rounded according to the MathContext settings.
def scale : Int
Returns the scale of this BigDecimal.
def setScale (scale : Int, mode : Value) : BigDecimal
def setScale (scale : Int) : BigDecimal
Returns a BigDecimal whose scale is the specified value, and whose value is numerically equal to this BigDecimal's.
override def shortValue : Short
Converts this BigDecimal to a short. If the BigDecimal is too big to fit in a byte, only the low-order 16 bits are returned. Note that this conversion can lose information about the overall magnitude of the BigDecimal value as well as return a result with the opposite sign.
def signum : Int
Returns the sign of this BigDecimal, i.e. -1 if it is less than 0, +1 if it is greater than 0 0 if it is equal to 0
def to (end : BigDecimal, step : BigDecimal) : Inclusive[BigDecimal]
Like until, but inclusive of the end value.
def to (end : BigDecimal) : Partial[BigDecimal, Inclusive[BigDecimal]]
Like until, but inclusive of the end value.
def toBigInt : BigInt
Converts this BigDecimal to a scala.BigInt.
def toBigIntExact : Option[BigInt]
Converts this BigDecimal to a scala.BigInt if it can be done losslessly, returning Some(BigInt) or None.
def toByteExact : Byte
This BigDecimal as an exact value.
def toIntExact : Int
def toLongExact : Long
def toShortExact : Short
override def toString : java.lang.String
Returns the decimal String representation of this BigDecimal.
def ulp : BigDecimal
Returns the size of an ulp, a unit in the last place, of this BigDecimal.
def unary_- : BigDecimal
Returns a BigDecimal whose value is the negation of this BigDecimal
def until (end : BigDecimal, step : BigDecimal) : Exclusive[BigDecimal]
Same as the one-argument until, but creates the range immediately.
def until (end : BigDecimal) : Partial[BigDecimal, Exclusive[BigDecimal]]
Creates a partially constructed NumericRange[BigDecimal] in range [start;end), where start is the target BigDecimal. The step must be supplied via the "by" method of the returned object in order to receive the fully constructed range. For example: 
   val partial = BigDecimal(1.0) to 2.0       // not usable yet
   val range = partial by 0.01                // now a NumericRange
   val range2 = BigDecimal(0) to 1.0 by 0.01  // all at once of course is fine too
