isPracticallyUndefined

public static boolean isPracticallyUndefined(float x)

The "isPracticallyUndefined" methods are for dealing with externally undefined values that only approximate the exact Java float or double UNDEFINED representation. They would be used at the time the external representation is received from the data base to immediately reset the value correctly before it becomes part of the data set.

isPracticallyUndefined

public static boolean isPracticallyUndefined(double x)

getUndefinedFromPracticallyUndefined

public static float getUndefinedFromPracticallyUndefined(float x)

Return the true UNDEFINED value for a float that is numerically close to it.

getUndefinedFromPracticallyUndefined

public static double getUndefinedFromPracticallyUndefined(double x)

Return the true UNDEFINED value for a double that is numerically close to it.
