Syntax 1

public BigDecimal( String val ) throws NumberFormatException

Description

Constructs a BigDecimal from a string containing an optional minus sign followed by a sequence of zero or more decimal digits, optionally followed by a fraction, which consists of a decimal point followed by zero or more decimal digits. The string must contain at least one digit in the integer or fractional part. The scale of the resulting BigDecimal will be the number of digits to the right of the decimal point in the string, or 0 if the string contains no decimal point. The character-to-digit mapping is provided by Character.digit. Any extraneous characters (including whitespace) will result in a NumberFormatException.

Syntax 2

public BigDecimal( double val ) throws NumberFormatException

Description

Translates a double into a BigDecimal. The scale of the BigDecimal is the smallest value such that (10**scale * val) is an integer. A double whose value is -infinity, +infinity or NaN will result in a NumberFormatException.

Syntax 3

public BigDecimal( BigInteger val )

Description

Translates a BigInteger into a BigDecimal. The scale of the BigDecimal is zero.

Syntax 4

public BigDecimal( BigInteger val**, int** scale ) throws NumberFormatException

Description

Translates a BigInteger and a scale into a BigDecimal. The value of the BigDecimal is (BigInteger/10**scale). A negative scale will result in a NumberFormatException.
