Parameters:

val - Value

Returns:

Distance

doubleValue

public abstract double doubleValue()

Get the value as double.

Returns:

same result as getValue().doubleValue() but may be more efficient.

floatValue

public float floatValue()

Get the value as float.

Returns:

same result as getValue().floatValue() but may be more efficient.

intValue

public int intValue()

Get the value as int.

Returns:

same result as getValue().intValue() but may be more efficient.

longValue

public abstract long longValue()

Get the value as long.

Returns:

same result as getValue().longValue() but may be more efficient.

shortValue

public short shortValue()

Get the value as short.

Returns:

same result as getValue().shortValue() but may be more efficient.

byteValue

public byte byteValue()

Get the value as byte.

Returns:

same result as getValue().byteValue() but may be more efficient.
