Class Numeric

      edu.harvard.hul.ois.jhove.module.pdf.Numeric

public class Numeric
extends Token

Class for Tokens which represent PDF numbers. Numeric values are stored as double if they have a real value, or as int if they have an integer value. The implementation notes state that the maximum value of an integer on a 32-bit machine is 2 ^ 31 - 1. However, they also say that byte offsets have a limit of 10 decimal digits, which is a larger value. So we store integer values as long.
