Constructor Detail

AutoMedFloat

public AutoMedFloat(java.lang.String text)

Create a new AutoMedFloat from text, creating a null value if the text cannon be parsed.

AutoMedFloat

public AutoMedFloat(float value,
                    int bits)

Create a new AutoMedFloat from a 32 bit floating point value.

AutoMedFloat

public AutoMedFloat(double value,
                    int bits)

Create a new AutoMedFloat from a 64 bit floating point value.

AutoMedFloat

public AutoMedFloat()

Create a new AutoMedFloat that is null in value

Method Detail

floatValue

public float floatValue()

Return the value of this AutoMedFloat as an float

doubleValue

public double doubleValue()

Return the value of this AutoMedFloat as an double

Specified by:

doubleValue in class AutoMedType

add

public AutoMedFloat add(AutoMedFloat v)

Return the sum of two AutoMedFloats.

subtract

public AutoMedFloat subtract(AutoMedFloat v)

Return the difference of two AutoMedFloats.

divide

public AutoMedFloat divide(AutoMedFloat v)

Return the division of two AutoMedFloats.

multiply

public AutoMedFloat multiply(AutoMedFloat v)

Return the multiplication of two AutoMedFloats.

toString
