DecimalNumberImpl

public DecimalNumberImpl(org.antlr.runtime.Token token)
Method Detail

dump

public String dump(int indent)
Description copied from interface: INRLAstNode
Dump the AST and its children for debugging purposes

Specified by:
dump in interface INRLAstNode
Overrides:
dump in class Antlr3NRLBaseAst
Parameters:
indent - the indentation count, 0 on first call
Returns:
the AST as a string

getNumber

public double getNumber()
Description copied from interface: IDecimalNumber
Return the number.

Specified by:
getNumber in interface IDecimalNumber
Returns:
the number

getNumberAsBigDecimal

public BigDecimal getNumberAsBigDecimal()
Description copied from interface: IDecimalNumber
Return the number as a BigDecimal. This ensures there is no loss of precision when parsing decimal numbers.
