 multiplicand), with rounding according to the context settings. | 
BigDecimal | 
BigDecimal.negate(MathContext mc)
Returns a  
BigDecimal whose value is (-this),

BigDecimal whose value is (+this),
 with rounding according to the context settings. | 
BigDecimal | 
BigDecimal.pow(int n,
   MathContext mc)
Returns a  
BigDecimal whose value is
 (thisn). | 
BigDecimal | 
BigDecimal.remainder(BigDecimal divisor,
         MathContext mc)
Returns a  
BigDecimal whose value is (this %
 divisor), with rounding according to the context settings. | 
BigDecimal | 
BigDecimal.round(MathContext mc)
Returns a  
BigDecimal rounded according to the
 MathContext settings. | 
BigDecimal | 
BigDecimal.subtract(BigDecimal subtrahend,
        MathContext mc)
Returns a  
BigDecimal whose value is (this - subtrahend),
 with rounding according to the context settings. | 
| Constructor and Description | 
|---|
BigDecimal(BigInteger unscaledVal,
          int scale,
          MathContext mc)
Translates a  
BigInteger unscaled value and an
 int scale into a BigDecimal, with rounding
 according to the context settings. | 
BigDecimal(BigInteger val,
          MathContext mc)
Translates a  
BigInteger into a BigDecimal
 rounding according to the context settings. | 
BigDecimal(char[] in,
          int offset,
          int len,
          MathContext mc)
Translates a character array representation of a
  
BigDecimal into a BigDecimal, accepting the
 same sequence of characters as the BigDecimal.BigDecimal(String)
 constructor, while allowing a sub-array to be specified and
 with rounding according to the context settings. | 
BigDecimal(char[] in,
          MathContext mc)
Translates a character array representation of a
  
BigDecimal into a BigDecimal, accepting the
 same sequence of characters as the BigDecimal.BigDecimal(String)
 constructor and with rounding according to the context
 settings. | 
BigDecimal(double val,
          MathContext mc)
Translates a  
double into a BigDecimal, with
 rounding according to the context settings. | 
BigDecimal(int val,
          MathContext mc)
