Class FloatingData

java.lang.Object

          net.sf.cb2java.copybook.data.FloatingData

public class FloatingData

extends ValueData

Floating point representations are hardware specific so the precision that is supported by the underlying type may vary from platform to platform. For most normal uses Java floats or doubles should be safe to use but it's possible that there may be a loss of precision if the underlying platform does not follow the IEEE 754 spec.

Because not all floating types are the same in COBOL BigDecimal is the 'natural' type for this class, however, numbers with fraction portions that are not representable in binary will be rounded on setting the data.

FloatingData

public FloatingData(Floating definition)

constructor

Parameters:

Method Detail

getBigDecimal

public java.math.BigDecimal getBigDecimal()

gets the big decimal representation of the value

setValueImpl

public void setValueImpl(java.lang.Object data)

Description copied from class: Data

called by setData after validate is called

Specified by:

setValueImpl in class Data

Parameters:

data - the data to set

setValue

public void setValue(java.math.BigDecimal data)

toString

public java.lang.String toString()

Specified by:

toString in class ValueData

getValue

public java.lang.Object getValue()

returns the internal data as a BigDecimal

Specified by:

getValue in class Data

getFloat

protected float getFloat()

returns the internal data as a BigDecimal

getDouble

protected double getDouble()

returns the internal data as a BigDecimal

translate

protected java.lang.Object translate(java.lang.String data)

Description copied from class: Data

Converts the String to the underlying Data type's 'natural' type. The String must be understood by the data type.
