Uses of BigDecimal in java.math

 

Methods in java.math that return BigDecimal
static BigDecimal	BigDecimal.valueOf(long unscaledVal, int scale)           Translates a long unscaled value and an int scale into a BigDecimal.
static BigDecimal	BigDecimal.valueOf(long val)           Translates a long value into a BigDecimal with a scale of zero.
BigDecimal	BigDecimal.add(BigDecimal val)           Returns a BigDecimal whose value is (this + val), and whose scale is max(this.scale(), val.scale()).
BigDecimal	BigDecimal.subtract(BigDecimal val)           Returns a BigDecimal whose value is (this - val), and whose scale is max(this.scale(), val.scale()).
BigDecimal	BigDecimal.multiply(BigDecimal val)           Returns a BigDecimal whose value is (this * val), and whose scale is (this.scale() + val.scale()).
BigDecimal	BigDecimal.divide(BigDecimal val, int scale, int roundingMode)           Returns a BigDecimal whose value is (this / val), and whose scale is as specified.
BigDecimal	BigDecimal.divide(BigDecimal val, int roundingMode)           Returns a BigDecimal whose value is (this / val), and whose scale is this.scale().
BigDecimal	BigDecimal.abs()           Returns a BigDecimal whose value is the absolute value of this BigDecimal, and whose scale is this.scale().
BigDecimal	BigDecimal.negate()           Returns a BigDecimal whose value is (-this), and whose scale is this.scale().
BigDecimal	BigDecimal.setScale(int scale, int 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.
BigDecimal	BigDecimal.setScale(int scale)           Returns a BigDecimal whose scale is the specified value, and whose value is numerically equal to this BigDecimal's.
BigDecimal	BigDecimal.movePointLeft(int n)           Returns a BigDecimal which is equivalent to this one with the decimal point moved n places to the left.
BigDecimal	BigDecimal.movePointRight(int n)           Moves the decimal point the specified number of places to the right.
BigDecimal	BigDecimal.min(BigDecimal val)           Returns the minimum of this BigDecimal and val.
BigDecimal	BigDecimal.max(BigDecimal val)           Returns the maximum of this BigDecimal and val.

 

Methods in java.math with parameters of type BigDecimal
BigDecimal	BigDecimal.add(BigDecimal val)           Returns a BigDecimal whose value is (this + val), and whose scale is max(this.scale(), val.scale()).
BigDecimal	BigDecimal.subtract(BigDecimal val)           Returns a BigDecimal whose value is (this - val), and whose scale is max(this.scale(), val.scale()).
BigDecimal	BigDecimal.multiply(BigDecimal val)           Returns a BigDecimal whose value is (this * val), and whose scale is (this.scale() + val.scale()).
BigDecimal	BigDecimal.divide(BigDecimal val, int scale, int roundingMode)           Returns a BigDecimal whose value is (this / val), and whose scale is as specified.
BigDecimal	BigDecimal.divide(BigDecimal val, int roundingMode)           Returns a BigDecimal whose value is (this / val), and whose scale is this.scale().
int	BigDecimal.compareTo(BigDecimal val)           Compares this BigDecimal with the specified BigDecimal.
BigDecimal	BigDecimal.min(BigDecimal val)           Returns the minimum of this BigDecimal and val.
BigDecimal	BigDecimal.max(BigDecimal val)           Returns the maximum of this BigDecimal and val.

BigDecimal	SQLInput.readBigDecimal()           Reads the next attribute in the stream as a java.math.BigDecimal object.
BigDecimal	CallableStatement.getBigDecimal(int parameterIndex, int scale)           Deprecated.
BigDecimal	CallableStatement.getBigDecimal(int parameterIndex)           JDBC 2.0 Gets the value of a JDBC NUMERIC parameter as a java.math.BigDecimal object with as many digits to the right of the decimal point as the value contains.
